摘要: Abstract Lightweight concrete filled steel tubular (L-CFT) member is the new type of consisting hollow tube and lightweight concrete. This study aims to investigate bending-shear behavior tubular, L-CFT, member, which lighter than normal N-CFT, member. The two test parameters, large diameter-to-thickness shear span ratios are selected. influence ratio on L-CFT deep beam under through asymmetric four-point loading discussed. Moreover, methods predict types capacities provided. elasto-plastic biaxial stress plane condition also mentioned. obtained experimental strengths agreed with proposed strength based upon RC theory.
