Displacement-based earthquake design of unreinforced masonry walls in two-way bending

目前的无筋砌体（URM）建筑抗震设计是建立在验算墙体和连接的强度超过地震惯性力的基础上的。墙体抗弯强度的保守估计用于解释砌体结构质量的广泛变化。本项目提出了一种新的基于位移的URM墙体设计方法，该方法不那么保守，更直接，更可靠，更容易应用基于力的方法。因此，与目前评估建筑物中URM墙体的地震脆弱性的技术相比，该方法节省了大量成本。

Current design of unreinforced masonry (URM) buildings for earthquake loading is based on checking that the strength of walls and connections exceeds the earthquake-induced inertia forces. Conservative estimates of wall bending strength are used to account for the wide variability in the quality of masonry construction. This project proposes to develop a new "displacement-based" design methodology for URM walls which is less conservative and more direct, reliable and easier to apply the the force-based method. Hence, this method offers substantical cost savings over current techniques for the assessment of the seismic vulnerability of URM walls in buildings.
