In this paper, the application of equivalent simplified calculation model of isolated structure in super high-rise building is studied. In this paper, the characteristics of isolation structures with different height width ratio are analyzed, and the relationship curve between the limit value of height width ratio of isolation structure and the distance of isolation support is established. From the curve, we can estimate the limit height of the isolated structure when the bearing does not produce tensile stress under different seismic intensities. This paper also analyzes the influencing factors of the height width ratio limit, and puts forward the method of increasing the height width ratio limit. In this paper, a vertical stiffness correction model of isolation bearing is proposed. Compared with the shaking table test results and time history analysis, the modified model can truly reflect the mechanical properties of the isolation bearing.

The reinforced concrete (RC) frame-tube structure considered in the study has two towers with lapping transfer columns. The lapping transfer columns, considering aesthetic requirement in elevation, lead to a complex vertical force transfer system. The large irregularity in elevation, according to Chinese code, necessitates a detailed study. A 1/15-scaled model of the high-rise building was tested on a shaking table to evaluate its seismic performance. The model was subjected to earthquake inputs representing frequent, basic, rare, and extremly rare earthquakes. The results of shaking table test in terms of the global and local responses as well as the dynamic properties are presented. The tests demonstrate that the designed structural system satisfies the pre-defined performance objectives and the lapping transfer columns have good seismic peformance. To better control seismic damages of the building, some suggestions for improving the design of this structure are also put forward at last.

Based on the principle of real-time substructure shaking table test, an interactive numerical computation method which built the calculation model of each substructure in different software programs was proposed for seismic analysis of equipment–high rise structure–soil systems in order to account the effect of nonlinear soil. Considering that the response of soil under strong earthquakes does not totally enter the nonlinear stage, a locally nonlinear soil model was introduced as the numerical substructure, and the equipment–high rise structure subsystem was treated as an experimental substructure in this method. The equation of motion for the equipment–high rise structure–soil system was derived through a combination of the branch modal substructure and linear–nonlinear hybrid constraint modal substructure approaches. A 13-layer steel framework system model is used as an analytical example that the equipment–high rise structure system and local nonlinear soil computing model are built by MATLAB and ANSYS, respectively. The time histories of the system dynamic responses were obtained by interactive numerical computation, to investigate the effects of equipment–high rise structure–soil interaction on the seismic performance of the equipment and structure.

Story Building

<p>The paper discusses results of shaking table tests on an in-scale high-rise building model. The purpose was to calibrate a dynamic numerical model for multi-hazard analyses to investigate the effects of floor acceleration. Accelerations, because of vibration of non-structural elements, affect both the comfort and safety of people. The research investigates the acceleration effects of both seismic and wind forces on an aeroelastic in-scale model of a multi-story building. The paper discusses the first phase of experiments and gives results of floor accelerations induced by several different base seismic impulses. Structural analyses were first performed on the full-scale prototype to take soil-structure interaction into account. Subsequently the scale model was designed through aeroelastic scale laws. Shaking table experiments were then carried out under different base accelerations. The response of the model and, in particular, amplification of effects from base to top are discussed.</p>

Based on the equivalent mass-spring model and considering the coupling effect between creep soil and prestressed anchors, the dynamic calculation model of prestressed anchors with frame structure is established. The soil mass is expressed in the form of concentrated mass. The action of the frame structure on the soil is treated as a parallel coupling of a linear spring and a linear damper, and the free section of the anchor is treated as a linear spring. Considering the creep characteristics, the soil is regarded as a Generalized Kelvin body and the anchoring section of the anchor is regarded as an equivalent spring body, which are coupled in parallel. Considering the effect of slope height, the dynamic calculation model is solved and the seismic response is analyzed. Finally, an engineering example is used to verify the calculation method in this paper, and the results are compared with the shaking table test and numerical simulation. It shows that the calculation model proposed in this paper is safe and reasonable for the seismic design and analysis of the slope supported by prestressed anchors with frame structure.
