This means load re-distribution on the anchors due to elastic deformations of the anchor plate are not considered - the anchor plate is assumed to be sufficiently stiff, in order not to be deformed when subjected to the design loading. PROFIS Engineering calculates the minimum required anchor plate thickness with CBFEM to limit the stress of the anchor plate based on the assumptions explained above. The proof if the rigid anchor plate assumption is valid is not carried out by PROFIS Engineering.

Masonry wall must not have any damages (neither visible nor not visible)! While installation, the positioning of the anchors needs to be maintained as in the design phase i.e. either relative to the brick or relative to the mortar joints. • The effect of the joints on the compressive stress distribution on the plate / bricks was not taken into consideration. • If no significant resistance is felt over the entire depth of the hole when drilling (e.g. in unfilled butt joints), the anchor should not be set at this position or the area should be assessed and reinforced. Hilti recommends the anchoring in masonry always with sieve sleeve. Anchors can only be installed without sieve sleeves in solid bricks when it is guaranteed that it has not any hole or void. • The accessories and installation remarks listed on this report are for the information of the user only.

OWNER’S ACKNOWLEGMENT AND VERIFICATION OF INFORMATON DIRECTIONS: Read and initial each statement below to signify you understand or verify this information. _____1. I understand a frequent practice of unlicensed persons is to have the property owner obtain an “Owner -Builder” build- ing permit that erroneously implies that the property owner is providing his or her own labor and material personally. I, as an Owner-Builder, may be held liable and subject to serious financial risk for any injuries sustained by an unlicensed person and his or her employees while working on my property. My homeowner’s insurance may not provide coverage for those injuries. I am willfully acting as an Owner -Builder and am aware of the limits of my insurance coverage for injuries to workers on my prop- erty. _____2. I understand building permits are not required to be signed by property owners unless they are responsible for the construction and are not hiring a licensed Contractor to assume this responsibility. _____3. I understand as an “Owner-Builder” I am the responsible party of record on the permit. I understand that I may protect myself from potential financial risk by hiring a licensed Contractor and having the permit filed in his or her name instead o f my own. _____4. I understand Contractors are required by law to be licensed and bonded in California and to list their license numbe rs on permits and contracts. _____5. I understand if I employ or otherwise engage any persons, other than California licensed Contractors, and the total value of my construction is at least five hundred dollars ($500), including labor and materials, I may be considered an “employer” under state and federal law. _____6. I understand if I am considered an “employer” under state and Federal law, I must register with the state and federa l government, withhold payroll taxes, provide workers’ compensation disability insurance, and contribute to unemployment com- pensation of each “employee.” I also understand my failure to abide by these laws may subject me to serious financial risk. _____7. I understand under California Contractors’ State License Law, an Owner -Builder who builds single-family residential structures cannot legally build them with the intent to offer them for sale, unless all work is performed by licensed subcontrac- tors and the number of structures does not exceed four within any calendar years, or all of the work is performed under contr act with a licensed general building Contractor. _____8. I understand as an Owner-Builder if I sell the property for which this permit is issued, I may be held liable for any f inan- cial or personal injuries sustained by any subsequent owner(s) that result from any latent construction defects in the workma n- ship or materials.

Minimum equivalent thickness required (in.) for standard northwest block wall ratings. Cores can be filled with grout, loose- -33 (ref. 4) or C-331 (ref. 5) requirements. TEK NOTE June 2016 Concrete Masonry Fire Resistance Concrete masonry is a noncombustible construction material possessing excellent fire-resistive properties. The resistance of concrete masonry to fire is well established by extensive testing to be a function of the type of aggregate used in the manufacture of the masonry units and their equivalent thickness. The rated fire-resistive periods for block walls can be determined by knowing this information and complying with Table 721.1(2), item number 3 of the International Building Code (IBC)(ref. 1). This is an alternative code- recognized method to the Underwriters Laboratory (UL) listing service. The equivalent thickness of concrete masonry assemblies, TEA, shall be computed as the sum of the equivalent thickness (average solid thickness as shown in Figure 1) of the concrete masonry unit, TE, plus the equivalent thickness of finishes, TEF, per code equation 7 - 6. TEA = TE + TEF (Equation 7 - 6) TE = V/LH where: Concrete masonry units (CMU) are commonly manufactured with a combination or blend of aggregate types. The International Building Code covers this condition by reference to standard TMS 216 (ref. 6). The minimum equivalent thickness value required for a desired fire rating can be determined by interpolating between requirements for different aggregate types in proportion to the percentage by volume of each aggregate used in manufacture. For example, for a standard block manufactured in the Northwest, which is approximately a 60/40 percentage blend of gravel and pumice aggregates, the required equivalent thickness values to achieve various fire ratings are shown in Table 2. V= net volume of masonry unit, in.3 (per ASTM C-140)(ref. 2) L = specified length of masonry unit, in. H = specified height of masonry unit, in. Equivalent thickness values for concrete masonry units conforming to ASTM standard C-90 (ref 3) meeting minimum required faceshell and typical web dimensions are shown in Table 1. Individual block manufacturers may have higher values based on a greater solid percentage. Nominal Block Width (in.) Block Core Treatment Empty or Fill Cores Solid Fill 1 4 2.7 3.6 6 3.1 5.6 Fire Rating 1 Hr. 2 Hr. 3 Hr. 4 Hr. 2.52 3.80 4.78 5.60 Figure 1. Concrete masonry unit equivalent thickness TE = 0.53 (7.625) = 4.04 in. If this hollow unit is 53% solid, the equivalent thickness (TE) is 4.04 inches. Table 3. Fire-resistance ratings of concrete masonry walls1 in the concrete block mix. Walls can be filled with grout, loose- -33 or C- . If the aggregate blend is changed to 70/30 to produce architectural unit, the fire rating is decreased hours. Application of the information in Tables 1 and 2 results in the listing of concrete masonry wall fire ratings in Table 3. Fire-Resistance Rating Increases/Decreases Finishes on concrete masonry walls can increase the fire- resistance rating. If wall finishes are used see IBC Section 722.3.2. Contributions of plaster or gypsum wallboard shall be determined from IBC Tables 722.2.1.4(1) and 722.2.1.4(2). Additional masonry wythes can also increase the fire-resistance rating of wall assemblies. Equation 7-7 of IBC section 722.3.3 addresses multi-wythe masonry walls. If the specified CMU density is increased, the proportions of blended aggregates will vary from the 60/40 percentage example used in Tables 2 and 3. There will be more heavy weight aggregate and less lightweight aggregate in the concrete mix and some ratings may decrease (see footnote 3 in Table 3 above). Fire Resistance Testing It is important to remember that the term “fire-resistance rating” is a legal term utilized by building codes to regulate building construction. While the ratings are based upon a standard fire test exposure, assemblies having the same rating, but constructed with different materials, often perform quite differently. Fire-resistance rated wall assemblies are commonly evaluated using ASTM Standard E-119 (ref. 7). The standard is used to determine the wall’s hourly fire rating and to indicate its expected durability during a fire. A wall tested according to E-119 undergoes both fire exposure and water hose-stream testing. The hose-stream test provides a meaningful measure of durability during a fire. It provides an indication of how well the wall can endure fire exposure as well as falling debris, pressure waves due to explosions, actual fire hose-streams and other rough usage that often occurs during a real fire, which can never be truly replicated in a laboratory test. According to ASTM E-119, the hose-stream exposure test may be performed in one of two ways. The basic test, typically used for frame wall construction, permits the use of two identical assemblies. The first one is subjected to the fire exposure test to determine its hourly fire-resistance rating. The second specimen is subjected to the fire exposure test for only one half the recorded rating period (but not for more than one hour). The second assembly is then removed and hose-stream tested. The more rigorous optional E-119 test method is commonly used for concrete masonry assemblies. This second test method requires the hose-stream to be applied to the same specimen that has undergone the full fire exposure test. Nominal Wall Width (in.)

Two-hour rated walls subjected to the hose- stream test of ASTM E-119. Concrete Masonry Wall Gypsum Wall By including both hose-stream test procedures, ASTM E-119 includes two distinct levels of durability performance. Clearly, application of the hose stream to a specimen that has undergone the full fire-exposure test is more rigorous and indicates a high level of durability. In a real building fire, a wall assembly doesn’t get a second chance to perform. In typical code applications, however, no distinction is made between the two tests and, as a result, assemblies that pass the duplicate specimen test are assumed to have the same “durability rating” as those passing the more rigorous optional test method. This is an erroneous assumption (see Fig. 2 ). Control Joints Movement control joints in fire rated wall assemblies should also be rated. Figure 3 shows the types of control joints available in accordance with standard TMS 216 to maintain the fire-resistance rating of the wall in which they are constructed. Improving Fire Safety Hourly fire ratings alone do not adequately address structural performance and durability under real world fire conditions. This means that some “rated” walls may not be able to provide the level of fire safety expected. However, concrete masonry’s inherent non-combustibility coupled with excellent strength and durability combine to provide fire rated walls whose performance is exceptional. Masonry walls offer the following fire safety benefits: • Protect building egress • Prevent fire-spread within a building and to adjacent buildings • Maintain the structural integrity of bearing walls • Provide firefighter protection Building owners and designers should consider the advantages offered by durable, noncombustible concrete masonry wall systems over other systems having equivalent fire-resistance ratings. The added protection provided to both life and property should not be overlooked. To provide the best fire protection for occupants and the greatest opportunity to escape, the masonry industry recommends that building codes require a balanced design approach comprised of three key elements: fire detection, suppression, and containment by compartmentation. Fire detection includes the installation of smoke detectors and fire alarms; active fire suppression includes the use of sprinkler systems; and fire containment includes interior firewalls, and exterior walls built of noncombustible fire- resistant materials such as concrete masonry. Concrete masonry construction can contain the spread of fire while not emitting toxic gases or smoke, allowing precious additional time for building occupants to exit. Unfortunately, building and fire codes have strayed significantly from this balanced design approach to fire safety. Codes often except (trade- off) the requirements to use noncombustible construction when certain fire sprinkler requirements are met. Today’s building code officials should be encouraged to develop code provisions that provide an improved level of redundancy for life safety and property protection and to eliminate sprinkler trade-offs. Owners and designers should be aware of the benefits of balanced design. Consider the reliability of protection from only individual fire-safety components versus the redundancy provided by the complementary features of the balanced-design system. For example, in the event the sprinkler systems fails to properly operate during a fire, the built-in protection offered by concrete masonry fire-separation walls will help contain the fire until it can be controlled. Along with this built-in fire protection, concrete masonry provides property protection, and ensures building stability to allow occupants to safely exit. Without this level of protection, safety can be jeopardized. Figure 3.
