This paper deals with a case study of brick masonry veneer distress on a reinforced concrete high-rise structure. The key cause of distress was the absence of a movement joint at the underside of the shelf angle at each floor level. A computer model introduced by the authors in a previous analysis paper is used to investigate the effects of various parameters on differential movements and veneer stresses. The results indicate that the provision of movement joints of at least 3–4 mm/storey would have prevented a buildup of significant veneer stress. In the absence of a movement joint, veneer stresses were found to be high enough to result in distress as observed on the case study structure. The paper concludes with a discussion of repair considerations.

In recent years a growing number of masonry veneer distress cases have occurred on high-rise structures. These cases are now known to be caused by the omission of a differential movement joint between veneer and structure. This paper reviews how these distress problems have arisen in a historical context and then presents the various movement parameters and relationships that must be considered. A computer model was developed to predict differential movements and resultant stresses when inadequate movement joints are provided. The paper gives an overview of the model and describes its capabilities. The application of the model to a case study structure is treated in a subsequent paper.

AbstractThis case study focuses on the evaluation of the collapse rates of various types of reinforced concrete structures (residential and industrial) as observed from the data collected in Romania after the Mw 7.4 Vrancea earthquake of March 4, 1977. The results of the analyses show that the largest collapse rates were attributed to elevated reinforced concrete silos and water tanks. Moreover, the majority of the collapsed elevated reinforced concrete water tanks were full at the moment of the seismic event. Very small collapse rates were observed for high-rise residential RC structures and for the multi-storey industrial RC structures.

AbstractUnder strong earthquakes, reinforced concrete (RC) walls in high-rise buildings, particularly in wall piers that form part of a coupled or core wall system, may experience coupled axial tension–flexure loading. In this study, a detailed finite element model was developed in VecTor2 to provide an effective tool for the further investigation of the seismic behaviour of RC walls subjected to axial tension and cyclic lateral loading. The model was verified using experimental data from recent RC wall tests under axial tension and cyclic lateral loading, and results showed that the model can accurately capture the overall response of RC walls. Additional analyses were conducted using the developed model to investigate the effect of key design parameters on the peak strength, ultimate deformation capacity and plastic hinge length of RC walls under axial tension and cyclic lateral loading. On the basis of the analysis results, useful information were provided when designing or assessing the seismic behaviour of RC slender walls under coupled axial tension–flexure loading.

Setting the late poured band is to solve different settlement between high-rise buildings and to settle the reinforced concrete body temperature--contraction stress. In addition, it effectively avoids the harmful cracks caused by the reinforced concrete body. So it is vital to set the late poured band and organize the correct construction. This paper aims at elaborating types of post pouring belt, construction preparation, construction technique, quality and so on.
