Strength of Joints and Joint Assemblies of Reinforced Concrete Multistory Frames under Loads of the Seismic Type (Prochnosti Stykov I Uzlov Zhelezobetonnykh Karkasov Mnogoetazhnykh Zdanii Pri Nagruzakakh Tipa Seismicheskikh)
An investigation was made of the seismic strength of several types of joint assemblies with continuous joints between precast columns and cross beams under cyclic loads with a coefficient of asymmetry, rho = P min/P max = 0.1. Specially constructed test joint assemblies, consisting of stub columns and cantilevered beams with welded reinforcement, with and without brackets, were tested to failure under eccentric compression and compression with shearing force. Conclusions were: (1) Monolithized column joints (that is, grouted with mortar and exposed ends of reinforcement welded) for multistory buildings have adequate strength and are recommended for seismic areas, but they must be located away from the contact edge of the joint assembly to reduce bending moments. (2) The tested joint-assembly designs, except Series IV, can be used for multistory buildings, but in seismic areas semiautomatic welding of reinforcement in copper and graphite forms is generally recommended, although several hand welding processes may be used under special conditions.
