Due to the relatively low stiffness of the column against horizontal translation and rtotation at its connection with truss such an assumption abou support condition in analysis of truss is consistant with the design of coulmun.
Hello all We design the trusses by assuming the support conditions as one end pinned & other roller. If we design the columns, by assuming tied together at top by trusses thus having the cantilever deflection of all the columns at top to be equal. (As suggested by SP 38 too) My question is how the truss will be able to transfer hor. force to the columns as one end of the truss is considered to be roller. It can transfer hor. force to the col. at the end, which is considered as pinned.
