    New to risa3d instability

    Hi there, I am new to modeling in Risa 3d. I have made this model of a small braced frame building. Typically I would model each lateral line in 2D and asses the deflection/strength that way. Our office has recently added RISA 3d so I thought I would model the whole structure. However, I am...

    Column Shear reinforcing

    I am getting some strange results with my concrete column shear reinforcing. Concrete design is returning 5192mm2/m weak axis shear reinf and 8147mm2/m strong axis shear reinforcing. This is after specifying confinement bars with 20M bars @300oc when defining the column frame section. Does...

    Wall base connectivity to wall below

    Hi there, I am modeling a multi story building with concrete bearing/shear wall. The window openings are inconsistent from 2nd to ground floor so ive entered grids and drawn in the walls and openings in the correct locations. However, when I run the model, the base of the 3rd floor wall does not...

    SAFE- Reaction Forces

    I have modeled a 30' transfer slab in SAFE 16 with gravity loads (from a 4 story building above). The gravity loads have been input by assigning loads to null beams and areas. However, when running the analysis, it produces some rather large joint reactions in the x and y direction. This seems...

    Risa 3d Wood wall Axial loading

    Hi there, I have been playing around with Risa3d for wood shearwalls. I am having trouble getting distributed axial load to transmit into the studs. I have tried applying the udl directly to the top of the wall panel, as well as creating a dummy member as recommended in this tutorial...
