Recent studies have shown that in the event of a strong earthquake, partially grouted (PG) masonry walls would most likely not perform according to code expectations. The research reported herein is focused on introducing an economically competitive design detail to enhance the seismic performance and safety index of PG reinforced masonry shear walls. Besides the conventional design details of single grouted vertical cells with single bond beams, two other details called double grouted vertical cells with double bond beams, and double grouted vertical cells with single bond beams plus joint reinforcement, were constructed and tested in this study. Test results demonstrated that the single grouted wall failed in a low ductility shear-dominated mode, while the modified design details resulted in a change to the high ductility shear failure mode. Results of nonlinear static and incremental dynamic analyses showed that using the proposed enhanced detail can significantly improve the seismic performanc...

Funicular structures are structural skeletons designed using methodologies that analyze the flow and direction of forces, which can be categorized as compression, tension, or a combination of both. They are not only elegant, resembling naturally occurring forms, but also highly efficient and can be built with minimal use of relatively low-strength materials, thus minimizing their negative environmental impact. This book presents an in-depth overview of the theoretical foundations and practical methods of designing funicular structures for maximum efficiency. Beginning with a foundation and introduction to funicular structures for those new to the subject, the book then provides in-depth coverage of cables, arches, shells and vaults, domes, and spatial structures. Chapters explain the theory behind funicular structures in 2D, spatial funicular structures in 3D and examine their structural behavior. Recent and historically famous structures from around the globe are analyzed, and their potential design methods revealed through step-by-step, visual explanations. Structural analysis of funicular structures in different forms are also presented to demonstrate pitfalls and common errors. Tracing the various methods of designing funicular structures, including the latest computational tools, this book provides a solid foundation for students of architecture, structural design, civil engineering, landscape design, and environmental design, to embark on their own funicular design projects. <!----> <!----> <!----> <!---->
