REMINDER: The truss must be cut into two different sections. You can choose either one to
solve as you will get the same answer. Since there are three equations available,
you can't cut more than three members

CMU. The wall height is 18feet. It is assumed to be simply supported. The wall is to be designed for an out-of-plane seismicload of 52 lbs./ft.2, which can act in either direction. The wall also supports a roof dead load of600 lbs./ft. and a roof live load of 300 lbs./ft. along the wall length. The roof loads have aneccentricity of 2.5 inches. Since there is seismic load, load combinations (6) and (7) in Chapter 2of ASCE 7-22 should be considered. In these two load combinations,horizontal seismic loadhE =andvertical seismic loadvE = . You may ignorevE in this problem for simplicity. The masonryhas a specified compressive strength of 2,500 psi. (a) Use the strength design provisions of TMS402 to determine the size and spacing of the vertical bars needed. Use the P-δ analysis method inSection 9.3.4.4.2 of TMS 402 to determine Mu.
