Abstract

Based on the experimental research of six high-strength shale ceramsite concrete beams and two normal density concrete beams,the calculation method of carrying capacity of normal section of high-strength shale ceramsite concrete beams was put forward.Based on the coefficient of internal force couple arm and coefficient of non-uniform distribution of longitudinal bar strain which were obtained from the experimental data,the calculation methods of bending rigidity of section,deflection and crack width of high-strength shale ceramsite concrete beams were put forward.The results may be referenced for revising relevant specifications and practical engineering.
