PER ASCE 7-16 SECTION 11.B.3 ALTERATIONS <br />EXISTING LATERAL FORCE RESISTING SYSTEM IS EXEMPT <br />FROM ANALYSIS SINCE NEW SEISMIC FORCE IS <br />LESS THAN 10% GREATER THAN EXISTING SEISMIC FORCE. <br />"Alterations are permitted to be made to any structure without requiring the <br />existing structure to comply with this standard provided the alterations comply <br />with the requirements for a new structure. Alterations that increase the <br />seismic force in any existing structural element by more than 10 percent or <br />decrease the design strength of any existing structural element to resist <br />seismic forces by more than 10 percent shall not be permitted unless the <br />entire seismic force-resisting system is determined to comply with this <br />standard for a new structure." <br />End of Calculations <br />EXISTING BASE SHEAR <br />Loyd W.
