Welcome to Shearwalls

WoodWorks® Shearwalls is a software application intended for structural engineers performing lateral wind and seismic design of wood structures that are six or fewer stories in height.

Shearwalls' interactive graphical interface allows you to quickly specify building blocks, walls, openings, roofs, hold-down connectors, loads, and forces.

Shearwalls has automatic routines for

Shearwalls presents its design results in a sequence of organized and easy-to-read tables, and as shear wall diagrams in Elevation view.

Please refer to the resources described in Help Documentation for operating instructions and program capabilities and limitations. Other resources are described in Technical Support and Training.

Shearwalls Versions and Design Codes and Standards

Shearwalls Version 13.1 conforms to the 2021 International Building Code (IBC) and the 2018 National Design Specification (NDS). It incorporates the ASCE 7-16 load generation and seismic design procedures, and the AWC Special Design Provisions for Wind and Seismic (SDPWS 2021) shear wall design provisions.

Shearwalls 12.3 and Shearwalls 11.2 are also available for those users in jurisdictions that have not yet adopted IBC 2021 or who wish to check designs made with the older design codes and standards. Shearwalls 2019 conforms to IBC 2018, NDS 2018, SDPWS 2015, and ASCE 7-16. Shearwalls 11.2 conforms to IBC 2015, NDS 2015, SDPWS 2015, and ASCE 7-10.

This On-line Help has been fully updated to incorporate the changes for SPDWS 2021 implemented in Version 13 and further program improvements with Version 13.1. Unless otherwise noted, the references in this Help are to NDS 2018, ASCE 7-16 and SDPWS 2021.
