摘要：

An experimental investigation was conducted to compare the shear strength of lightweight reinforced concrete beams with that of normal-weight concrete companion specimens. The experimental variables were type of coarse aggregate, concrete compressive strength, and distribution of transverse and longitudinal reinforcement. A total of twelve specimens with shear reinforcement were tested. Seven specimens were made with normal-weight aggregate concrete and five specimens were made with lightweight aggregate concrete. The target concrete strengths were 41 MPa and 69 MPa. Measured shear capacities were compared with calculated values according to the 1998 AASHTO LRFD Bridge Specifications (Interim 2001) and ACI 318-02 Building Code. The experimental findings have shown that both code-based methods produce conservative estimates of shear strength within the range of variables considered in the study.
