Development and testing of precast concrete beamtocolumn

Model Precast Concrete Beam-to-Column Connections Subject

Abstract. Experimental results of eight-scale model precast concrete beam-to-column connections are presented. The test specimens consisted of interior connections designed in accordance with the 1985 Uniform Building Code provisions for Seismic Zones 2 and 4. These tests constitute the second and third phases of a multi-year test program being

An Experimental Study on Precast Concrete Beam-to-Column

A new type of precast concrete exterior beam-to-column connection is introduced in this paper. The connection consists of a precast U-beam, precast column with corbel, and interlocking bars to connect the precast column and precast beam; these bars, act as the flexural reinforcement to withstand the hogging and sagging moment subjected during testing.

Precast Concrete Beam to Beam, Beam to Column Failures

Jun 28,  · In a precast concrete construction of structures, precast concrete beam to beam and beam to column connections are vulnerable points that fail when faced by the cyclic loading of earthquakes. During an earthquake, precast concrete beam and columns fail because of plastic hinge formation and non-ductility of the structure. This article addresses the problems and solutions related
