Multi-Storey Shear Walls. Design Example

Technical

Checking Vf,seismic for a Multi-Storey Shear Wall

Taking seismic effects into account in MASS can be confusing. Seeing factored shear forces scaled up by over 100% in some cases may seem larger than expected. The main post found here outlines the clauses being invoked here where the requirements are broken down into two parts: A and B. Read more…
