Efficient Detection

Based on the current methods of damage detection, a new detection damage model was proposed in order to search a more efficient detection method for reinforced concrete high-rise building damage induced by earthquake. This model is based on the regularity of change in the damping ratio of high-rise buildings, and the high order modes, mode participation coefficient and measure method of natural frequency, together with the type of structures, are taken into account in the model. The shaking test results for a model of reinforced concrete high-rise buildings show that the damage detection results based on the proposed model are close to the test results.

High Rise Building

In this research, a reduced scale model of the composite high-rise building with steel reinforced concrete column, steel beam and reinforced concrete core tube was designed and tested by using the shake table test technology. The acceleration and displacement of the model were measured during the tests. The cracking pattern and failure mechanism were illustrated. Above the shake table test, the finite element analysis of the test mode was carried out. The main effort of the numerical analysis was focused on the selection of the nonlinear models. Based on the experiment results and the strategy of considering nonlinear property of the beam-column joint and the short beam of the concrete core wall were proposed. It is proved that the proposed strategy is effective and economical for seismic behavior assessment of such composite high-rise building structure system.

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.
