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.

目前，无筋砌体（URM）建筑物的地震荷载设计是基于检查的墙壁和连接的强度超过地震引起的惯性力。 保守估计墙的弯曲强度是用来解释砌体结构质量的广泛变化。 本计画提出一种新的以位移为基础的URM墙设计方法，此方法较力为基础的方法保守性更低，且更直接、可靠且更容易应用。 因此，这种方法提供了大量的成本节约比目前的技术，用于评估建筑物中的URM墙的地震易损性。
