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

• exterior and upper story wall creation,
• joining of building blocks
• shear line generation
• floor area and building mass calculations
• roof layout
• wind and seismic load generation
• rigid and flexible diaphragm load distribution to shear lines
• distribution of forces within a shear line to wall segments
• force transfer around openings and force-transfer pier and strap forces
• deflection analysis and story drift
• equalization of deflections on a shear line
• hold-down and drag strut force determination
• hold-down design
• shear wall design, including worst-case wind/seismic, worst-case rigid/flexible diaphragm, and wall design groups

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

Shearwalls 2019 (Version 12) conforms to the 2018 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 2015) shear wall design provisions.

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