For concrete column members, the load combination producing the maximum shear code check is reported in the Detail Report and corresponding Results spreadsheet. Since concrete is evaluated based on a batch solution, this can be useful when shear governs the design. RISAFloor Concrete tab of the Column Results spreadsheet: Column Detail Report: RISA-3D: Concrete Columns […]

The BS EN 1992-1-1:2004+A1:2014 has been implemented in RISA-3D version 16.0 and RISAFloor version 12.0. To select this code for your design, simply open the (Global) Model Settings and under the Codes tab select BS EN 1992-1-1:2004+A1:2014 for concrete: After running an analysis, the detail reports will display the code that the user has selected […]

In RISAFoundation v9, you can add a vertical offset for slabs or beams.  Traditionally, RISA uses centerline analysis which aligns all elements at their centerline.  This is a common structural analysis assumption as the loads will get transferred to the centerline even if there is difference in the sizes. In certain circumstances, it becomes necessary […]

RISAFloor ES allows you to model concrete slabs of any thickness.  However, there might be sections of the building that require a thicker slab.  The icon is shown below and it will allow you to draw a Polygon or Rectangular shape. You can use this tool to change the thickness anywhere in the slab. The […]

Construction joints involving shear keys or dowels are common practice for slab-on-grade and mat foundations. Examples of this detail are shown below: When two different slab elements touch each other in RISAFoundation they are assumed to have a full moment connection, as though they were placed monolithically. However, it is easy to specify a pinned […]
