    Push-over: which action group?

    Hi ! I've done a push over analysis on a xlam structure formed by 3 floors. I've applied two action groups: one for the modal deformation and the other one proportional to masses. I obtained two push over curves. The first one has low resistance (F max is lower= 382 kN)but it has more ductility...

    Friction isolator : wall-soil

    Hello! I'm modeling an xlam wall with push over analysis. I've to implement the friction between soil and wall through a friction isolator. I've followed this procedure : 1 creation of a new link 'friction isolator' with u1 and u2 non linear degrees of freedom 2 I use an high stiffness for u1...

    Links between two vertical xlam shells - a problem of offset

    Thank You for your answers. I've to model this xlam wall with friction at the soil . I activates the u1 and u2 direction but there is a problem : what values of friction stiffness I use in u1 and u2 direction? This friction isolator approximates the friction between wall and soil. The friction...

    Links between two vertical xlam shells - a problem of offset

    Thank you so much! I have another question about friction isolator on Sap2000. Ive a friction coefficient equal to 0.4. I model a friction isolator (non linear) with these following proprieties. Is it correct? From results I notice that there is no difference between results with isolator and...

    Links between two vertical xlam shells - a problem of offset

    I plan to use "two joint link". How long do the links? Is it important their lenght?

    Links between two vertical xlam shells - a problem of offset

    Hello, I've to model an xlam wall. This one is divided into two walls: first plane wall (2.95 m) and second plane wall (2.95 m). These walls are connected with non linear multiplastic link (hold downs and angle brackets). There is a problem: when I draw the wall above, Sap2000 merges this one...

    Force controlled push over analysis sap2000

    Yes, I can choose "displacement controlled" or "force controlled" in the analysis option. The problem is that I can only select "full load" in force controlled push over and If multiplastic link (hold down or angle bracket) has a softening behaviour there is no convergence and so the analysis...

    Force controlled push over analysis sap2000

    Hi guys, I've to do a "force controlled" push over analysis on a wood wall with sap2000. How can i do this? I am able to use "displacement controlled" analysis but not force controlled. I want to increase my top force until the wall is in crisis and the links reach their respective ultimate...
