Seminar Description

Codes and standards are easy to interpret for box-type structures, but not for the recent advances in wood mid-rise construction, such as increased heights and stories, openings, and irregularities. This web seminar will discuss those tough-to-handle code issues facing designers today, including:

  1. How to deal with penetrations and openings in diaphragms and shear walls
  2. Negotiations to resolve the “wall vs opening” battles
  3. The rigid, flexible, or semi-rigid diaphragm question
  4. Open front structures, cantilevered diaphragms, and blocking of diaphragms
  5. Horizontal and vertical irregularities
  6. Seismic joints and when they are required
  7. Building drift, shear wall, and diaphragm deflections: importance and advice on how to compute relatively simply
