The Analysis Of Concrete Temperature Crack And Computer Simulation

With the use of concrete, many new problems in concrete structures are gotten up. The temperature crack is one of these new problems.On the basis of the primary concepts of thermal conduction and thermal physical property of concrete material, the causes resulting in temperature stress of the concrete structures are analyzed, a compute model for the temperature stress of concrete structures is set up by using the finite element theory, the principles to check of the structure are also given up. Employing VC computer code and Fortran computer code, a programmer on simulating concrete temperature crack is compiled, then a concrete beam with the temperature load is analyzed.ANSYS software is applied to simulate the crack of concrete beam in this paper, some helpful approach on applying ANSYS software in simulating the crack of concrete structures are given.Finally, a conclusion and summary is made in the thesis and some effective measures to reduce the temperature stress and control temperature crack are proposed. And also some suggestions on the research are proposed.
