Friction Joints for Seismic Control of Large Panel Structures

Abstract

'The research reported herein was conducted while Dr. Pall was Research Associate at Centre for Building Studies, Concordia University, Montreal, Quebec, In steelframed buildings or cast-in-place concrete structures, reliance is placed on the ductility of the structure to dissipate energy while undergoing inelastic deformations. In large panel construction, it is difficult to develop flexural ductility due to the limited continuity in the vertical steel, and although in some European systems the precast panels are jointed to give vertical continuity, the suitability in general of this type of construction for seismic regions is often questioned. The current seismic codes
