Experimental studies on earth pressure on culvert pipe of RC circular pipe;

The behavior of 20 circular tubed reinforced concrete(CTRC) columns was investigated experimentally under static axial compression.

In order to clarify the effect of experimental parameters(strength of concrete,width-thickness ratio,arrangement of reinforcing bars and ribs) on mechanical characteristics of RCFT(reinforced concrete filled steel tube),bending test on circular beam specimens of hollow steel tube,CFT(concrete filled steel tube) and RCFT were carried out.

Experimental and Theoretical Research on Mechanical Behaviors of RC Circular Pipe;

Through computation and analysis of reinforced concrete bifurcation pipe,this paper has given stress distribution of fork part,and analyzed the influence that the change of fork angle has on stress distribution.

3-D FEM is applied to analyze the reinforced concrete bifurcation pipe of the transferring water series of a hydropower station,the stress distribution is worked out and the reinforcement is schemed considering the stress.

Finite element method is adopted to analysis the reinforced concrete bifurcation pipe in some hydropower station,considering six combined operating conditions in construction and operating processes,the distributions of the stress for bifurcation pipe and wall rock are worked out,and analysis and explain of calculation results is presented.
