    Etabs Slab stresses

    that distibution of stresses makes sense. You should read the values outside the cross section of the column (not inside joints). Moreover, you should not stick on local stress peaks, but assume a mean value per a unit surface. Analysis and Design of arbitrary cross sections Reinforcement...

    Wood building analysis 3D software?

    You can use a general finite element analysis program, eg SAP and assign the properties of wood material and section. Finally, after obtaining the analysis results, you can proceed to the check of the cross sections using a general timber cross section application, for example this one. A...

    ASTM A496 rebar instead of A615 rebar?

    I thinks the difference has only to do with their plasticity (ductility) Analysis and Design of arbitrary cross sections Reinforcement design to all major codes Moment Curvature analysis http://www.engissol.com/cross-section-analysis-design.html

    Modeling Masonry walls using SAP2000

    You should use shell elements and assign the corresponding material properties to the sections you will use. You should also take care of the fact that the connection of the precast slab to the masonry should be modeled correctly. Analysis and Design of arbitrary cross sections Reinforcement...

    Beams

    As SAP proceeds to a biaxial design for every structural element, even if it is a column, beam or brace, I would not concern much. On the other hand, SAP uses by default a buckling length factor equal to 1.0 for braces and beams. So, if buckling is critical, you may then want to override that...
