#### Why Are The Steel Beam Deflections So Large?

When solving a RISA-3D model with hot rolled steel members using AISC 360 code, some member deflections are 20% larger than expected due to a stiffness reduction applied to certain members. Read More

#### How can I find the deflection of plates?

Below is a model of a flat concrete slab made of plates. In order to ensure adequate serviceability of the slab, you may need to check the deflection of the slab between columns. Read More
