ORDINANCE NS-2182 PAGE 22 Footnotes: (1) Allowable shear stress may be increased by addition of ten (10) per cent of the axial stress due to the weight of the wall directly above. Design compression and tension values. Design compressive stresses of analysis specified in this section shall be one hundred (100) psi. Design tension values for unreinforced masonry shall be assumed equal to zero. (h) Testing of rod anchors. Five (5) per cent of the existing rod anchors utilized as all or part of required wall anchors shall be tested in pullout by an approved testing laboratory. The minimum number tested shall be four (4) per floor, with two (2) tests at walls with joists framing into the wall and two (2) tests at walls with joists parallel to the wall. The test apparatus shall be supported on the masonry wall at a minimum distance of the wall thickness from the anchor tested. The rod anchor shall be given a preload of three hundred (300) pounds prior to establishing a datum for recording elongation. The tension test load reported shall be recorded at one-eighth (1/8) inch relative movement of the anchor and the adjacent masonry surface. Results of all tests shall be reported. The allowable resistance value of existing anchors shall be forty (40) per cent of the average of the reported test loads. (i) Tests for wall anchorage. Qualification tests, for devices used for wall anchorage shall be tested with the entire tension load carried on the enlarged head at the exterior face of the wall. Bond on the part of the device between the enlarged head and the interior wall face shall be eliminated for the qualification tests. The resistance value assigned the device shall be twenty (20) per cent of the average of the ultimate loads. SECTION 34: That section 8-2500 of the Santa Ana Municipal Code is hereby amended to read as follows: Sec. 8-2500. Adoption by reference. There is adopted by the city that certain code known as the International Association of Plumbing and Mechanical officials Uniform Solar Energy Code, 1991 Edition, save and except that portion entitled "Part I, Administrative." The said code is adopted and incorporated as fully as if set forth at length herein as provided for in section 419 of the Charter of the city. Any provision of this article amending the "Uniform Solar Energy Code" or "solar energy code" shall be construed as amending the above-said code edition. The above-said code edition, together with all other provisions of this article, shall be known as the solar 22
