Dear all, I found that the above error was actually because of some problems in my version. Further i would like to know how we can apply distributed moving load in risa 3d. thanks in advance best regards G

Dear all, I have build a truss model in RISA 3D V6. I applied a -1KN moving load along bottom chords and perform the envelop solution. To my surprise, I found little Bending moment in bottom chords and huge amount of axial force in other members in contrast of just -1KN of applied load. I build...

Dear all, Please someone clear my confusion on how does sap calculates the time period of building when we choose to program determined time period in earthquake load pattern.I generally use IS1893 seismic code. my next query is how does sap determines design moment in column design. In column...

Thanks unodinoi for your response and answer. please do clear my next confusion. i have assign the beam with dimension of 300mm x 300mm and the slab with 110m. i also assign beam with top center in cardinal insertion point. my confusion is does it mean the t beam is now of depth equal to 300 +...

Dear all, please someone tell how the seismic weight of structure and base shear can be shown. For it, i summed up the support reactions for 1.5(DL+LL) load combination and divide it by 1.5. This total reaction is near to the manual seismic weight calculation. but the base shear (which i...

Dear JoshPlum, thanks for the response. I thought i should reinstall the program. but it does not work.

Dear all, when i tried to design the concrete beam, a warning message popouts stating the "could not use 2 minimum flexural bars. no code check possible" and "unable to provide minimum steel as per global parameters". Beam is not designed here. Also how the member forces, beam and column...
