摘　　要：通过对10根桁架式钢骨混凝土简支梁的静力荷载试验,研究各试件的弯曲破坏过程、裂缝开展模式等破坏形态,分析各试件的承载能力、截面应变分布规律等受力性能。研究表明:梁纵筋配筋率和含钢率是影响桁架式钢骨混凝土梁抗弯性能的主要因素。Based on the static load tests of 10 steel reinforced concrete（ SRC） simple beams encased steel truss,all the failure patterns of specimens were studied,such as bending process,crack propagation mode; and the bearing capacity of the specimens,and their strain distribution of the cross section were analyzed. Study showed that the ratio of longitudinal reinforcement and the steel ratio of steel reinforced concrete beam were the main factors affecting the flexural performance of the SRC beams.
