Abstract
The current philosophy for seismic design lies on utilization of inelastic behavior of structural elements for extreme load. Whereas, wind design is based on elastic behavior for both levels of serviceability and strength. Wind load on tall buildings is so large and in some cases even exceeds the seismic load. Hence, allowance of inelastic behavior could result in more logical and economical design and is a key to developing more resilient performance-based wind design (PBWD). Here, the nature of wind and seismic loads is compared and substantial connections between components of current wind design and performance-based seismic design (PBSD) are explored. As a result, a new methodology for the design of tall buildings based on integrated PBSD and PBWD is introduced. In this seminar, recent development and procedures on the non-probabilistic reliability-based method of PBWD, particularly on the practical nonlinear dynamic analysis techniques, will be presented.
