ABSTRACT

Reinforced concrete buildings constitute a significant portion of construction in Australia. Many existing buildings in Australia and other low to moderate seismic regions have been designed with little to no consideration for ductile detailing. The majority of these buildings also possess vertical irregularities, which can exacerbate their vulnerability in an earthquake event. The seismic performance of shear wall and frame dual systems possessing discontinuities in frame elements in the form of ductility and failure mechanism has been assessed. And design recommendations in terms of response modification factors and designation of appropriate methods of analysis have been provided.

摘要

钢筋混凝土建筑构成了澳大利亚建筑的重要组成部分。澳大利亚和其他中低地震区的许多现有建筑物在设计时几乎没有考虑延展性细节。这些建筑物中的大多数还具有垂直不规则性，这可能会加剧它们在地震事件中的脆弱性。已经评估了具有延性和破坏机制形式的框架元件不连续性的剪力墙和框架双系统的抗震性能。并就响应修正因素和指定适当的分析方法提供了设计建议。
