RISAFloor Concrete Floor Slabs can design be transferred into RISA-3D for lateral design using either a Rigid Diaphragm or Semi-Rigid diaphragm. In RISA-3D, the wind and seismic loads are calculated and then applied into the diaphragm level to distribute the forces to the Lateral Resisting System. For example, looking at the plan view of a […]

The Detail Report is the best place to start to investigate the reinforcement design.  It will present the forces for the Total Design Strip which is the summation of forces over the entire Design Strip.  The Total Design Strip is broken into regions of reinforcement design; Column Strip, Mid-Rt and Mid-Left. Inside the Design Strip, […]

Cantilever Slab 1

Concrete buildings often have large cantilevers. In RISAFloor ES, the Support lines can be drawn to support points but also they can be drawn as cantilevers (shown below). The reinforcement design for the cantilevered section assumes that there will be a positive moment along the distance of the cantilever. This assumption forces the top rebar […]

In RISAFloor ES, you draw a support line from support point to support point to define the Design Strips. The program will automatically create Design Strips based on the tributary width. When you have walls in the model, it is often a question of how you draw in the support lines. Design strips are drawn […]
