Shearwalls 2020, Update 4

Shearwalls 2020, Update 4 (Version 11.4) was a service release update released on December 22, 2023 which provided several new features along with numerous bug fixes and small improvements.

In particular the update introduced the following improvements:

• Input, design check, and deflection calculations for proprietary or non-wood shear resisting elements. Note that the ability to manually enter rigidities or ignore height-to-width ratios was removed for standard wood shear walls, as these were intended to allow for proprietary elements.
• Design for compressive resistance of wall bottom plate under end stud pack.
• Automatic generation of dead loads on wall lines using wall self-weights and supported weights entered for each wall.
• Control of amount of dead load to be distributed to shear wall end chords
• Maximum of 7 levels rather than 6 to allow you to model rooftop structures
• More accurate calculation of hold-down/compression force offset, with application to hold-down/compression force moment arm and amplification of anchorage term in deflection equation.
• Calculation of crushing component of deflection equation.
• Calculation of bending term in deflection equation for unequal no. of end studs.
• Updated Simpson hold-down database and present hold-down names in the output tables more readably.

A detailed description of the changes is not yet available.
