In addition to the post- earthquake reconnaissance, BFRL focused its efforts primarily on post-earthquake fire and lifelines and on moment-resisting steel frames. Forming a joint university, industry, and government partnership, BFRL initiated an effort to address the problem of the rehabilitation of existing buildings to improve their seis- mic resistance in future earthquakes.

This design guide- line is a result of that joint effort. BFRL is the national laboratory dedicated to enhanc- ing the competitiveness of U. The research conducted as part of this industry, university, and government partnership and the resulting recommendations provided herein are intended to fulfill, in part, this mission.

The input and suggestions from all those who contributed are greatly appreciated. No members or buildings collapsed as a re- sult of the connection failures and no lives were lost. Nevertheless, the occurrence of these connection fractures has resulted in changes to the design and construction of steel moment frames.

The work described herein addresses possible design modifications to the WSMF connections utilized in pre- Northridge structures to enhance seismic performance.

  4. Description:.

It is intended that welds and bolts, being considerably less ductile, will not fracture. The beam-to-column moment connections should be designed, therefore, for either the strength of the beam in flexure or the moment correspond- ing to the joint panel zone shear strength. From to the UBC pre- scribed a beam-to-column connection that was deemed to satisfy the above strength requirements. This "prescribed" detail requires the beam flanges to be welded to the column using complete joint penetration CJP groove welds. The beam web connection may be made by either welding di- rectly to the column or by bolting to a shear tab which in turn is welded to the column.

A version of this prescribed detail is shown in Figure 1. Although this connection Figure 1. The fractures of "prescribed" moment connections in the Northridge Earthquake exhibited a variety of origins and paths. In general, fracture was found to initiate at the root of the beam flange CJP weld and propagate through either the beam flange, the column flange, or the weld it- self.
