Time Effect Calculation for Construction Process of Steel Reinforced Concrete Structures

Abstract:

Based on the mechanical behavior of the steel reinforced concrete (SRC) structures, the method to use the restraint between master and slave nodes to deduce substructure model of SRC structures was introduced, and the problem of the steel and concrete co work under creep was solved. The creep calculation method in combination with the ajusted effective modulus method(AEMM) and the finite element method was adopted, and a numerical simulation program SRCCM based on the Visual C++ and ObjectARX was developed for simulating the construction process of high rise SRC structures. It was validated by the general finite element software. And the construction process of a practical engineering example was analyzed. The analysis results indicate that the substructure element model of the restraint between the master and the slave nodes can reflect the actual mechanism of the SRC structure. Based on this computational model, this program which can simulate the construction process of high rise SRC structures can be applied to practical projects.
