The main components which affect the earthquake damage grades classification of multistory masonry buildings and the damage characters are summarized and analyzed through the statistics and analysis of a large number of previous earthquake damage data. According to the standard of earthquake damage grades classification, the damage numbers of each component of multistory masonry buildings under...

Accurate modeling of masonry has been a major concern of the researchers in the past decades. Besides reinforced and unreinforced masonry structures, masonry can be found in frame structures as infill panels which are used as partitions and/or external walls. These elements role as a part of structure and introduce a large degree of nonlinearity into the system. In this study, a micro-modeling ...

Two modeling techniques for practical nonlinear static analysis are implemented to support the development and usage of a new Limit Design method for special reinforced masonry shear walls. The new seismic design alternative is under consideration for future versions of the building code requirements for masonry structures in the U.S. The proposed simplified models were applied to a planar one-...

Masonry is one of the world’s most durable construction materials. Masonry structures can remain in service for hundreds or even thousands of years. Masonry structures often outlive their designers, their original design documents, and their original functions. When historic masonry structures are evaluated for preservation, adaptive use, or additions, there are numerous questions that may aris...

This paper aims to provide information on rammed earth and masonry mortars of the Fernandina defensive Wall Lisbon, Portugal, which was built in second half 14th century. No previous exists concerning materials construction techniques used this structure, is essential increase knowledge define requirements for a reliable conservation. An experimental campaign carried out samples extracted nine ...

Our research focuses on how new computational tools and design methods can support the design process of masonry buildings. Specifically we discuss the potential of parametric modeling technologies to promote innovation by embedding knowledge on masonry construction as both generative rules and checker functions. Their goal is to inform designers on the feasibility of their intents on early sta...

This study investigates the influence of uncertainty in material properties on in-plane lateral behavior and capacity stone masonry walls via a stochastic discontinuum analysis framework. The framework is demonstrated 3D numerical assessment an unreinforced (URM) wall using form Monte Carlo simulations. random parameters considered this are prism compressive strength masonry, tensile units join...

In contrast to the low-level use of silicone polymers as additives, silicone resins can be major components of the coating. Here they are used as binders or co-binders, imparting important benefits such as durability throughout the life of the coating. Silicone resins offer resistance to weathering in paints for exterior surfaces such as bridges and metal cladding on buildings. They also provid...

To understand the seismic damage characteristics of bottom frame-wall buildings and to study their seismic performance, the seismic damage outcomes of  bottom frame-wall structures in Du jiang weir by the Wen chuan earthquake on May 12,2008, China were field observed and studied. The assesment of the seismic damage to the bottom frame-wall masonry in Du jiang weir urban showed that the damage t...
