Abstract: This paper devoted to studying temperature joint in structures of reinforced concrete frame and bent. A nonlinear analysis program is made and improved specially for the study of reinforced concrete frame and bent under temperature load. Some reasonable values of joint distance are obtained for the frame and bent under high, middle and low temperature, and a design method of super-length reinforced concrete frame and bent under temperature load is presented.

Abstract: The authors present a procedure for the analysis of the stability and propagation of cracks in arch dams based on linear elastic fracture mechanics. A finite element method was used to calculate the stress intensity factors(KⅠ, KⅡ and KⅢ) of crack in the concrete arch dam, and fracture analysis for arch dams was carried out, which based on the criterion of three-dimensional mixed mode fracture of concrete from the experiment. The analysis method can be applied to evaluate the safety of the arch dam and improve the design for arch dam.
