Python library to simplify the connection with OpenSTAAD API

STSAD is used for checking calculation and design of steel structures composed of spatial members. The core part of the calculation is based on the spatial bar element, and the calculable structures include grid, shell and space truss. This program uses interactive man-machine interface, all operations are completed in the form of interface inte…

A simplified web-based platform, providing analysis and design of steel elements.

OpenSteel DSTV Viewer

Four 40 m towers built from the same 2.00 m3 of steel, shaken by one record turned up step by step until each collapses. Incremental dynamic analysis, JMA intensity, one gate deliberately failing and disclosed.

Reproducibility package: column removal attainability and capacity-path certificates for steel frames

Steel member and connection design to the Egyptian code ECP 205-LRFD (2008) in pure Python. Every check returns demand, capacity, utilisation, clause and governing limit state.

Steel beam web openings solved by plane-stress FEM: how much earlier first yield comes with a hole, by span

Four towers, four earthquakes of identical size (same peak ground velocity, same number of cycles). Only the frequency changes. A 0.04 g shake destroys a tower; 0.34 g breaks nothing.
