Development of a novel infill frame system using concrete masonry infills bounded by masonry frames

砌体墙填充钢或钢筋混凝土（RC）框架已广泛用于现代建筑结构，作为分隔空间的隔墙或建筑封闭的包层。据了解，如果墙体紧靠其边界框架，填充物将与框架相互作用并参与荷载分担，从而改变框架体系的结构性能。先前的研究表明，合理设计的填充为框架系统提供了显著的强度、延性和能量耗散，以抵抗各种类型的横向荷载-即使在相当大的裂缝之后。基于对砌体钢/RC框架的了解，本研究将开发一种新型的全砌体填充框架体系，并将其与传统的钢/RC框架体系进行比较，评估其结构性能。全砌体填充框架由一种材料制成，即砌体，其中砌体填充由砌体增强柱和系梁形成的砌体框架包围。框架和填充物的施工可以同时进行，这将简化和简化设计和施工过程，因为在钢或钢筋混凝土框架的情况下，不需要与混凝土或钢铁行业协调。全砌体填充体系旨在将边界单元（砌体柱和梁）和填充物结合在一起，在一种材料中形成有效的抗侧荷载体系。这将对砌体填充墙设计和施工的行业实践产生重大影响。本研究旨在开发具有不同结构形式和结构细节的全砌体框架体系，并通过大量的试验测试和数值研究来研究其在面内和面外荷载作用下的结构性能。预计在项目完成后，可以提出适用于行业实践的设计和分析方面的建设性建议。作为长期目标之一，本研究的实验和分析结果将用于建立一套统一的方程和设计图，以考虑将其纳入加拿大现行的全砌体填充框架砌体设计标准。

Masonry walls infilled steel or reinforced concrete (RC) frames have been commonly used in modern building construction to serve as either partitions for separating spaces or cladding for building closure. It is also understood that if the wall is built tight against its bounding frame, the infill will interact with the frame and participate in the load sharing, thus changing the structural performance of the frame system. Previous studies have shown that properly designed infills provide significant strength, ductility and energy dissipation for the frame system in resisting various types of lateral loads-even after considerable cracking. Built on the knowledge of the masonry infilled steel/RC frames, this research is to develop a novel, all-masonry infilled frame system and evaluate its structural performance in comparison with conventional infilled steel or RC frame systems. An all-masonry infilled frame is made of one material, i.e. masonry, where the masonry infill is bounded by masonry frames formed by masonry reinforced columns and tied beams. Construction of the frame and infill can occur at the same time, which will simplify and streamline both the design and construction processes as the need to coordinate with concrete or steel trades as in the steel or RC frame cases is eliminated. The all-masonry infilled system is intended to combine the boundary elements (masonry columns and beams ) and infills to form an effective lateral load resisting system in one material. This will have a significant impact on the industry practice in design and construction of masonry infill walls. This research is to develop the all-masonry frame system with different configurations and construction details and investigate its structural behaviour under both in-plane and out-of-plane loading through extensive experimental testing and numerical studies. It is expected that upon the completion of the project, constructive recommendations regarding design and analysis applicable to industry practice can be made. As one of the long-term objectives, the experimental and analytical results of the study will be used to establish a set of unified equations and design charts to be considered for inclusion in the current Canadian masonry design standard for all-masonry infilled frames.
