EXAMPLE 11. MASONRY WITH THE EQUAL FRAME METHOD

PARADEIGMA 11: " MASONRY M.I.P." 12 ⮚ AUTOMATIC PROCEDURE During the 'Automatic Process': In the solution m=0 only the vertical loads, i.e. the permanent G and mobile Q loads for the combination γG G+ψ2Q (where the value of γG depends on the SWD) are applied in order determine the initial stress of the beam. Subsequently, successive elastic analyses are performed where at each step the external horizontal seismic loads, which it is emphasised remain constant (i.e. their value does not change) in all solutions in the case of the orthogonal or inverted triangular distribution. Thus, according to the acting bending stress and the corresponding available bending strength in the members, the degree of static indeterminacy of the beam is continuously reduced by the creation of plastic joints, until finally the beam is transformed into a mechanism. The coefficients of the vertical loads are shown in the following combination. Then the iterative steps of Pushover begin to run. This is followed by an explanation of what happens at a random iteration step m and the same applies to the others.
