Multi-Storey

This video demonstrates the new multi-storey sections option in STRAP 2024.

Cold formed steel

This video covers how to define cold-formed steel sections with CROSEC software and import the sections into STRAP.  

Space Shell

A hemispherical shell with an opening at its top is loaded with point loads along its edge. As the geometry and loading are symmetrical, only one-quarter of the shell is modeled.

Seismic Analysis

The aim of the seismic analysis is to calculate the reaction of the model to earthquakes. This example describes the method to analyze the structure using Modal Analysis. Modal Analysis is the accepted method and is recommended by most design codes. The reaction of the model for each mode shape is calculated according to the response spectrum given by the seismic code.

Concrete Slab Deflection

Reinforced concrete slab deflection calculations based on cracked section, reinforcement ratio, and concrete creep & shrinkage.
