Cold Formed Steel Beam-Column Joints with Latex Layer Wrapping

Abstract

Columns are the primary element of a structure and are the first element to face the effect of lateral load during an earthquake. To resist such lateral seismic loading high strength and ductile steel frames with higher energy absorption capacity are generally preferred. The nominal ductile capacity of the steel can be boosted up with additional wrapping that could optimize the seismic performance significantly. The present work deals on the behaviour of cold-formed steel beam and cold formed steel column wrapped with latex layers for strengthening. The specimens were subjected to reversed quasi-static cyclic loading to partially simulate the seismic forces. Experimental results shows significant increase in strength capacity of beam-column with latex layer wrapping.
