Limit State Design Methodology for Reinforced Masonry

在美国和世界范围内，砖石建筑占建筑建筑的很大一部分。由于配筋砌体结构具有明显的经济性、防火安全性、建筑灵活性和施工简便性等特点，在中高地震区的使用日益增多。目前的砌体结构分析和设计以及材料和施工技术无法准确预测建筑物在横向荷载(如地震荷载)下的行为。本研究项目将发展一种地震作用下配筋砌体的极限状态设计方法。方法论将首先界定形成方法论所依据的假设的原则。第二，它将说明将用于执行这些原则的程序。极限状态设计方法的发展将为配筋砌块结构提供一种可与配筋混凝土和冷弯型钢相媲美的现代和经济的工具。

Masonry construction comprises a large portion of building construction in the U.S. and the world. Reinforced masonry construction use is increasing in moderate to higher seismic zones because of its apparent features of economy, fire safety, architectural flexibility, and ease of construction. The present state of masonry structural analysis and design and materials and construction technologies does not enable an accurate prediction of building behavior under lateral loads such as seismic loads. This research project will develop a limit state design methodology for reinforced masonry under seismic loading. The methodology will first define the principles which form the assumptions upon which the methodology is based. Second, it will describe the procedures that are to be used for the implementation of the principles. Development of the limit state design methodology will provide reinforced masonry construction with a modern and economic tool comparable to those available for reinforced concrete and cold-formed steel.
