<t>I didn't use the 'geometric nonlinearity' option.<br/>
I’ll try to explain better my problems. <br/>
First, using inelastic frames with inelastic material (in the core and in the cover) on a simply supported beam with uniform load (mass distribuited), I‘ve an action of compression along the ...

does anybody know why using, doubly clamped beam inelastic frame subject to a concentrated load in the middle span, i have an action of compression along the beam? when there should be?

<r>I'm in the elastic range. I did not apply additional mass to the section, only a mass distributed. varying the mass, the curvature and the reactions to the base increase linearly. so I think it's a software problem!<br/>

Does anybody know why using a 1 bay 1 story INELASTIC frame subject to a distributed load (distributed mass) I find the basic moments to be greater than those of a 1 bay 1 story ELASTIC frame?

<t>Hi I am using the rigid diaphragm through the use of Penalty Functions and Lagrange Multipliers for a static pushover analysis of a 3D building with plane (with element infrmFB) and I have different results. what is the right kind of constrain and what is the proper weight to assign to the ...

I did as you said but I get the same result taking into account the steel. I made a mistake putting Fc in kPa rather than in MPa.
thank you very much

<t>I'm doing an Eigenvalue analysis with CON_CC material and inelastic frame. The Young Modulus of the Help System (4700*fc^0.5) is not equal to the modulus calculated by SeismoStruct obtained from the section characteristics. In fact knowing EA and A, I can obtain E but it is different from 4700*fc ...

<t>I'm using the FB elements to do a cyclic pushover on a cantilever but as result, I cant't obtain a strength degratation, stiffness degratation and pinching for low axial loads.<br/>
I'm using the material stl_bl; concrete core- confined concrete; concrete cover- unconfined model.<br/>
I would ...
