that the column has section modulus of Ic and the beam has section modulus Ib=ß lc. Part a: use the force method to solve the reaction forces at A and B. (Note the reactionforces might be expressed as functions of B) (30%) Part b: based on your calculation from Part a, plot the variation of horizontal reaction force Ax with respect to B (15%); comment on why the reaction force Ax will change when the value of ß changes (10%) Part c: for the case of W24x84 for the beam and W14x211 for the column, what is the value of ß in this case? Calculate the reaction forces based on your derivation in part a and develop the moment diagram of the frame (15%); and use the virtual work method to calculate the horizontal displacement of C (15%) Part d: use SAP2000 to solve frame moment diagram and horizontal displacement of C for part c and compare with that from Part c; comment on possible difference (15%) Part e: what value should we take for ß to reduce the reaction force A, by 15% when compared with that from Part c?
