The first high-rise to be completed in Anhui Province in China adopts concrete-filled steel tubular frame- reinforced concrete tube composite structure, which can be classified as the out-of-codes hybrid structure. The structure analysis model is established through the use of the large-scale general finite element software ABAQUS. The dynamic plastoelastic analytical method based on explicit integration which is not theoretically simplified is used to directly imitate the nonlinear reaction of the structure subject to the seismic force. The deformation, internal force and the damage of the structure are studied through the dynamic plastoelastic time-history analytical method subject to the 7-magnitude rarely met earthquake. The calculation result indicates that the maximum inter-layer displacement angle is 1/366 on the X direction and 1/279 on the Y direction, both of which are smaller than 1/100, thus they meet the standards; except for the local cracks, no obvious compression damage is found on the main bearing wall, no plastic strain is found on the internal steel skeleton of the shear wall and the steel reinforcement of the edge member, and the shear wall is of good earthquake resistance performance. Lastly based on the loading and damage conditions of the components, suggestions for the improved design are put forward.

Seismic Vibrations

The reinforced concrete structures, not designed for seismic conditions, amid the past earthquakes have shown us the significance of assessment of the seismic limit state of the current structures. During seismic vibrations, every structure encountered seismic loads. Seismic vibrations in high rise building structure subjects horizontal and torsional deflections which consequently develop extensive reactions in the buildings. Subsequently, horizontal stiffness can produce firmness in the high rise structures and it resists all the horizontal and torsional movements of the building. Therefore, bracing and shear wall are the mainstream strategies for reinforcing the structures against their poor seismic behaviours. It is seen before that shear wall gives higher horizontal firmness to the structure when coupled with bracing however it will be another finding that in building model, which location is most suitable for shear wall and bracing to get better horizontal stability. In this study, a 15 story residential reinforced concrete building is assessed and analyzed using building code ACI 318-14 for bracing and shear wall placed at several different locations of the building model. The technique used for analysis is Equivalent Static Method by utilizing a design tool, finite element software named ETABS. The significant parameters examined are lateral displacement, base shear, story drift, and overturning moment.

In this paper, to verify the effectiveness and reliability of nonlinear numerical simulation based fiber model, two computer programs (CANNY 99 and IDARC-2D), in which shear wall elements were respectively simplified by fiber model and equivalent beam model, were adopted to perform the numerical simulations of 10 times shaking table tests of a nine story 1:6 scale frame-shear wall building model in this paper. Analysis model including beam, column and wall element in CANNY 99 is elaborated in detail. Test results are compared with simulation results in some aspects such as natural frequency, time history responses, and peak value responses. Results demonstrate that fiber model and Equivalent beam model can simulate the elastic-plastic earthquake response of R.C. wall structures very well.

The framed shear wall structure is a high-rise building structure with a transfer story, which has the poor seismic performance (upper rigid and lower flexible). The frame layer in the earthquake is prone to fail, which may even cause the collapse of building. In this paper, it uses the finite element software SATWE to explore the seismic performance of framed shear wall structure. Then we can draw the following conclusions: When the transfer story is set from the third layer to the ninth layer, the earthquake action of transfer story varies from 437.2kN into 564.9kN and is significantly higher than that of upper and lower layers; All the period of free vibration, angles of drift, bottom shear force, overturning moment of the structure have adverse effects on the structure, which are also detrimental to the structural seismic.

The finite element software ABAQUS is used to establish the seismic time-history analysis model of the utility tunnel joints. The viscoelastic boundary is employed to input the seismic wave through the equivalent nodal force. Considering the nonlinearity of the soil and concrete materials, the internal force of the cross-shaped utility tunnel is calculated, and the influence effect and influence range of the cross joints of the utility tunnel are also studied. Studies have shown that the internal forces near the cross joints increase significantly. The research has certain reference value for the seismic design of the cross joints in utility tunnel.

For a further study on the fire-resistant performance of steel plate shear wall under overall stage of fire, a numerical analysis model of steel frame filled with steel plate shear wall was built with the finite element software ANSYS. The stress and displacement distribution at different moments were calculated through the thermal structural coupling analysis acording to ISO-834 standard fire curve, by reasonable selection of the thermal parameters, which showed the highest temperature appeared on the heated side of the beam in the process of heating up, while the highest temperature in the stages of cooling and natural cooling appeared in the column-beam connection; The temperature of structure was elevated for 11minutes, then dropped for 64.5minutes and finally the structure was cooled in the air for 60.5minutes. The whole process shows that the lateral load-bearing capacity of the steel frame filled with steel plate shear wall was reduced by about 30 percent, compared to room temperature.
