Procedures for evaluation, repair, modification and design of welded steel moment frame structures, to reduce the risks associated with earthquake-induced damage. The recommendations were developed by practicing engineers based on professional judgment and experience and a preliminary program of laboratory, field and analytical.

Interim Guidelines and Advisory Number 2 (FEMA /B) The Interim Guidelines were the end product of the Phase 1 Steel Project. This document was developed to provide engineers and building officials with guidance on engineering procedures for evaluation, repair, modification, and design of welded steel moment frame structures, to reduce the risks associated with earthquake-induced.

A few fractures were discovered in some buildings, both in andbut their significance was not understood nor was their presence disseminated.

Bymost engineers believed they truly knew how to design earthquake-resistant structures and the Welded Steel Moment Frame (WSMF) structure was the gold standard for earthquake resistance.

Welded connections are widely used in beam-to-column connection of steel frame as rigid connections. But some diaphragms should be welded to the joints to obtain sufficient rigidity and strength, and it is observed in the recent earthquake damage, that the strain concentration in the vicinity of.

FEMA, `Interim guidelines: evaluation, repair, modification and design of welded steel moment frame structures' Report no. SAC, SAC Joint Venture, University Avenue, SuiteSacramento, CA   A large number of steel moment frames fractured at the welds of beam-to-column connections in earthquake.

As the weld damage behavior is a crucial factor for aseismic performance of steel frame connections, 20 local welded connections representing beam-to-column connections were tested under monotonic and cyclic loads to study the weld damage behavior in this paper.
