1 AIA/CES LU (HSW) or PDH credit. In current structural engineering practice in the west, there are significant variations in how the seismic analyses of light-framed multi-story wood buildings are performed. Improvement in analysis techniques, including the modeling of diaphragm and shear wall rigidity and computing building deflections, may be warranted. This presentation will include a summary of the application of flexible and rigid diaphragm design assumptions, current design practices and code criteria, calculation of shear wall deformations, shear wall modeling techniques and a step-by-step three-dimensional modeling procedure that incorporates non-linear shear wall behavior into a linear analysis.
Samuel Shiotani, SE a Senior Associate at Hohbach-Lewin, Inc. has worked as a structural engineer for over ten years specializing in the analysis and design of multi-unit wood framed residential buildings over post tensioned concrete podium slab construction. Throughout his career, Sam has provided innovative design solutions for many complex residential design projects located throughout Northern California. He has co-authored the SEAOC paper, Seismic Analysis of Light-Framed Multi-Story Residential Buildings and presented on the topic at the 2008 SEAOC convention.

LEARNING OBJECTIVES
AIA course #WEB059
| 1. |
Analyze the building code assumptions for flexible diaphragms and learn how to apply this knowledge to similar designs.
|
| 2. |
Explore the benefits of using a rigid diaphragm open front analysis for multi-story projects with stacked corridor walls.
|
| 3. |
Dissect the ASCE7-05 provisions relating to diaphragm and shear wall deformations.
|
| 4. |
Identify options for modeling multi-story shear walls to calculate deflection/deformation and how this can help them make better decisions for future projects.
