Current State

As high-rise buildings increase with height and slenderness, they become increasingly sensitive to dynamic vibrations, and therefore the natural frequency of vibration and damping ratio are very important design parameters, as they directly impact the design wind forces. Recent advances in sensing and computing technology have made it possible to monitor the dynamic behaviour of full-scale structures, which was not possible in the past. Full-scale validation of the dynamic properties is useful for high-rise designers to verify design assumptions, especially since recent measurements have shown that damping decreases as the height of the building increases, and in situ damping measurements have been lower than many currently assumed design values, potentially leading to unconservative designs. A 50-storey residential building in downtown Toronto, with a reinforced concrete coupled shear wall lateral load resisting system with outriggers was monitored using current state-of-the-art sensing technologies and techniques to determine, in situ, the dynamic properties under real wind loads. The in situ measurements were then compared with results obtained using current state-of-the-art computer modelling techniques.

Coupled Shear Wall

Coupling beams are essential structural elements of reinforced concrete coupled shear wall to resist earthquakes and other lateral loads. But many current reinforced concrete coupling beams are insufficient in resisting lateral loads due to their bad ductility. So a test of retrofitting methods of deep coupling beams with steel plates since their good performance in the ductility and deformation was made to find ways of improving the ductility of the beams, and the results of this retrofitting method prove good because of the incensement of the ductility, deformation and strength of the beams.

This paper is in two sections. The senior author discusses in the first section the reasons for some of the revised provisions in the current Ministry of Works, Structural Design Office, Code of Practice for the design of buildings, while the junior author deals in the second part with the application of these provisions to a reinforced concrete shear core building. He presents methods of designing and detailing a core for ductility and the effect of incremental damage to the spandrels in a coupled shear wall are examined.

Calculation Results

In this paper, seismic behavior of the frame-shear wall structure, which are respectively composed of the concrete filled steel tubular (CFST) and of the reinforced concrete (RC) column, have been studied under the conventional earthquake. Dynamic behaviors and earthquake responses including deformation and forcing of the CFST and RC structures are analyzed. Comparing the calculation results, the earthquake resistant behavior of the CFST structure has been evaluated synthetically, which may be referential for structure design.

Failure Dependence

It is necessary to study failure dependence problem in order to solve system reliability in the field of Civil Engineering. In this paper, failure dependence of reinforced concrete shear walls with different openings (including the whole shear wall, the shear wall with small opening, the coupled shear wall, the shear wall frame) are studied under fortification earthquakes using Monte Carlo method. The results demonstrate that failure of reinforced concrete shear walls with different openings is neither fully independent nor fully relevant. The number of failure dependent floors is about one-half total floors. The failure dependent floors are concentrated mainly in the upper part.
