Abstract:

The construction of high-rise building transfer story concrete girder belongs to the mass concrete, due to the concrete hydration heat temperature is often beyond the limited temperature, so need to make temperature calculation and temperature control of transfer story concrete girder in the construction process. This paper taking a steel reinforced concrete girder of a high-rise building transfer story as an example, using finite difference method to calculate the change rule of concrete temperature field along with age, then using nonlinear analysis program ANSYS simulation the mechanical performance of transfer beam under the action of loads and temperature stress during the construction. Analysis and calculation results should provide technical support for the construction of the steel reinforced concrete girder of the transfer story. Analysis shows that, at intervals of 12 days two laminated pouring of concrete in the construction process, will meet the requirements of temperature control.
