| Abstract |
Structural steel beams provide a viable alternative for coupling individual reinforced concrete wall piers. Such steel coupling beams offer more advantages for cases where height restrictions do not permit the use of reinforced concrete beams which are typically deep, or where the required capacities and stiffness cannot be developed economically by a concrete beam. To achieve better ductility and energy absorption than previously possible one, the use of steel link beams with their ends embedded in the reinforced concrete walls is proposed. Preliminary experimental results are reported for four two third scale reversed cyclic-loading tests of portions of ductile flexural walls coupled with steel link beams. The excellent performance, together with the ease of construction, demonstrate the feasibility of this alternative form of construction. To ensure ductile response, design and detailing guidelines for both the clear span and embedded portions of the link beams and the reinforced concrete embedment region are presented. An assessment, based on comparisons with other structural systems, of this new type of construction is presented. |
