This book was released on 2004 with total page 1268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unreinforced masonry (URM) construction, which has been widely used in the United States, presents a large threat to life safety and regional economic development because of its poor seismic resistance. In this research, the nonlinear seismic properties of URM structures were investigated via a quasi-static test of a full-scale two-story URM building and associated analytical and numerical studies. The tests of the 24ft. by 24ft. in plan 22ft. high URM building revealed that the damage was characterized by (1) the formation of large discrete cracks in the masonry walls and (2) the rocking and sliding of URM piers. Both of these results were consistent with the predictions based on individual component properties obtained in previous research. However, the tests also revealed significant global behavior phenomena, including flange effects, overturning moment effects, and the formation of different effective piers in a perforated wall. This global behavior greatly affected the response of the URM building tested. In order to understand the nonlinear behavior of the test structure, a series of analytical studies were conducted. First, at the material level, a mechanical key model was proposed to describe the failure of URM assemblages under a biaxial state of stress. Second, at the component level, an effective pier model was developed to illustrate the mixed failure modes of a URM pier and its nonlinear force-deformation relationship. Third, at the structure level, a nonlinear pushover model was built using the mechanical models at the material and component levels to describe the nonlinear properties of a URM building. This nonlinear pushover model and a three-dimensional finite element model were employed to analyze the test structure. Both gave results in good agreement with the test data. Improvements to current provisions for the evaluation of existing masonry structures were proposed.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Out-of-plane stability of unreinforced masonry walls is an important aspect to be taken into account in edification. This construction technique is widely used and it is one of the most vulnerable to seismic loading. It has been observed that damage produced by out-of-plane loadings is one of the most commonly produced failure mechanisms in seismic hazards. Despite of that, research into the out-of-plane stability of masonry walls is not yet enough developed. The aim of this research is to create a three-dimensional finite element model in order to study the latter problem. A parametrical study is performed on two numerical models under monotonic and cyclic out-of-plane loads. The influence of various geometrical and boundary conditions are studied in two different models of a single wall: a homogenized and a distinct model. A damage plasticity formulation, appropriate for brittle materials, is implemented for modeling the behavior of the wall. In the distinct model, frictional and cohesive interaction models are used for modeling the joints, which are constituted by mortar. Firstly a monotonic homogeneous distributed out-of-plane pressure is applied, in order to determine both, the resistance of the wall in terms of its force-displacement curve, and the failure mechanism. Next, the same model is submitted to cyclic out-of-plane uniform pressure and energy dissipation, as well as stiffness degradation is analyzed. Finally, some qualitative recommendations for the unreinforced masonry walls are derived from the results, with the purpose of maximizing the resistance in front of out-of-plane loading.
Book Synopsis Assessment of Perforated Unreinforced Masonry Walls Responding In-plane by : Charlotte Louise Knox
Download or read book Assessment of Perforated Unreinforced Masonry Walls Responding In-plane written by Charlotte Louise Knox and published by . This book was released on 2012 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this thesis describes the seismic assessment of perforated unreinforced masonry (URM) walls subjected to in-plane loading through accurate analysis of the wall lateral capacity and seismic demand. Current assessment methods for determining the capacity of perforated URM walls loaded in-plane, as outlined in the New Zealand guideline document (NZSEE 2006), are based on the assumption of infinitely rigid spandrel elements. From observations of damage after the 2010/2011 Canterbury earthquake sequence, this assumption has been proven to be invalid for certain perforated wall geometries. The research reported in this thesis was conducted with the primary aim of developing a practitioner focused assessment tool that accurately captured the global and local response of a perforated URM wall, with an emphasis placed on defining the influence of the spandrel geometry on the system level response of perforated URM walls responding in-plane. Pseudo-static cyclic testing of six full-scale pier-spandrel substructures and a two storey half-scale isolated perforated URM wall was conducted to investigate the variables which control spandrel failure mode and the influence of spandrel failure on the lateral capacity of multi-storey URM walls. Testing showed that the behaviour of the spandrel has a significant effect on the failure mode of the piers and hence the strength, stiffness and energy dissipation capacity of the system. A non-linear Equivalent Frame modelling method for perforated URM walls using the structural analysis software SAP2000 was appropriately validated using modelling results and experimental data. Spandrel behaviour was included within the modelling through the use of a moment-axial failure domain and a shear-axial relationship. Finally, a modified linear elastic procedure for assessing the demand on the in_ plane loaded walls of URM buildings with flexible diaphragms was developed and validated through the use of non-linear time history modelling.
Book Synopsis Masonry Bearing and Shear Walls Retrofitted With Overlay Composite Material by :
Download or read book Masonry Bearing and Shear Walls Retrofitted With Overlay Composite Material written by and published by . This book was released on 1998 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unreinforced masonry bearing and shear walls common in the Tennessee Valley Authority's (TVA's) switch-house structures have been found to be vulnerable to earthquakes. One technique to reduce the seismic vulnerability of these structures is to retrofit the masonry walls using the Hexcel-Fyfe TYFO(TM) system. This system consists of a glass fiber fabric combined with special epoxies to create a high strength, lightweight structural laminate. Hexcel-Fyfe TYFO(TM) can be designed to work in conjunction with existing walls to increase both the in-plane and out-of-plane seismic strength of the unreinforced masonry walls. To ensure that this technique will perform its intended purpose, the U.S. Army Construction Engineering Research Laboratories (USACERL) and TVA conducted seismic analysis and shake-table seismic testing using USACERL's Triaxial Earthquake and Shock Simulator. The results of seismic testing documented in this report show that applying the overlay material to one side of the unreinforced masonry wall will enhance its seismic resistance.

Book excerpt: Brick and Block Masonry - From Historical to Sustainable Masonry contains the keynote and semi-keynote lectures and all accepted regular papers presented online during the 17th International Brick and Block Masonry Conference IB2MaC (Kraków, Poland, July 5-8, 2020). Masonry is one of the oldest structures, with more than 6,000 years of history. However, it is still one of the most popular and traditional building materials, showing new and more attractive features and uses. Modern masonry, based on new and modified traditional materials and solutions, offers a higher quality of life, energy savings and more sustainable development. Hence, masonry became a more environmentally friendly building structure. Brick and Block Masonry - From Historical to Sustainable Masonry focuses on historical, current and new ideas related to masonry development, and will provide a very good platform for sharing knowledge and experiences, and for learning about new materials and technologies related to masonry structures. The book will be a valuable compendium of knowledge for researchers, representatives of industry and building management, for curators and conservators of monuments, and for students.
