The Analysis of Irregular Shaped Structures: Wood Diaphragms and Shear Walls, Second Edition

A complete guide to load path calculations in complex structures―fully updated for current practices and regulations

This thoroughly revised guide shows, step by step examples, how to calculate load paths―including for wind and seismic forces―in complicated structures. Written by a team of seasoned structural engineers and a certified building official, The Analysis of Irregular Shaped Structures: Wood Diaphragms and Shear Walls, Second Edition contains clear explanations of current topics, including cross laminated timber (CLT). You will get thorough coverage of newly developed structure types and new design solutions.
