On the basis of concept design that involves both structural and architectural performance, this paper puts forward a new reinforced concrete high-rise building structure with a new special-shaped shear walls, presents an experimental study of the seismic performance of the new special-shaped shear walls under low reversed cyclic loading using MTS electro hydraulic servo system. Compared with experimental results, a finite element analysis on this special-shaped shear wall structure, which considers the nonlinearity of concrete structure, is found suitable. It shows that the experimental results fairly confirms to the calculated values, which indicates that this new structure has advantages as good architectural function, big effective space, high overall lateral stiffness, fine ductility, advanced seismic behavior, etc.. That is, the close agreement between the theoretical and experimental results indicates the proposed shear wall structure has wide applications.

To optimize the design of RC frames with special-shaped columns, some special care should be given to the design of this type of structure. Designers should attach great importance to concept design by considering the structure as a whole to assimilate seismic energy. Ductility has to be guaranteed both for the structure and for the members. In high-rise buildings, frame-shear wall structure is preferred. Safety of L-shaped Corner columns is to be improved or otherwise cantilever beams can be designed to prevent progressive collapse.

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.

This article is probed into on the issue that the influence of border concealed column toward shear wall stiffness. Charge example indicates finite element that this text set up calculate model is acceptable. It is used the finite element method basic theory to compile finite element analysis procedure with four points rectangles unit to solve this problem. It can calculate the shear wall with concealed column’s displacement under the wind load to check the result it whether can be satisfied the design request. Using this procedure, this article carries on the finite element modeling analysis on a ten-floor building shear wall structure system. The procedure’s result and the software of ANSYS’s result tallies well, and it also be compared with the simplification computation’s result.

Post Tensioned

Torsion force is a load that is a applied to a building through torque. The torque applied creates a shear stress. If a torsion force is large enough, it can cause a building to undergo a twisting action. The main aim of the project is to study the effect of location of shear wall on torsional performance of symmetric and asymmetric high-rise building ,post tensioned slabs are being used in the construction of building hence the thesis also analyze these post tensioned slab structures by changing shear wall configuration. Post tensioned slab structures have weak resistance to lateral loads. so to provide stiffness to structures against lateral forces shear walls are used. A study of 30 storey building in zone III, is considered and determine various parameters like base shear, storey drift, and storey displacement.post-tensioning is a mature technology as it provide efficient, economic and elegant structural solutions for a wide range of applications. Post-tensioned flat slab could be a better option compared to RCC flat slab, in respect of the cost of project and time of construction. ETABS 2017 software is used for the analysis.

This paper analyzes the over-reinforcement of coupling beam in high-rise building structure design and proposes the relevant treatment methods and suggestions to provide references for designers. Coupling beam is a beam that is used to connect between wall limbs or wall limbs and frame columns in shear wall structures and frame – shear wall structures. A coupling beam generally has the features of small span, large cross section and high stiffness of the wall connected to it.
