    load combination is just a array of loads cases in your structure that serves to calculate forces, stresses and deflection but you don't have to assign load combination to the structure, you just have to assign loads (DEAD, LIVE, EARTHQUAQUE, ETC) and the load combination are independent from...

    rigid diaphragm

    thanks, but i don´t understand well, if i look the modal displacement (each one the different modes) the structure shows the displacement of the joint taking into account the diaphragm rigid condition... all of these movements are represent as the result of the spectrum analysis for each...

    hi: i'm modeling a 30 floor building in viña del mar (chile), i assigned membrane as a floor section, i have used a spectrum function as require NCh433of96 chilean seismic code. my problem is that i've assigned rigid diaphragm in all floors then i run the program an when y look joint...
