With the development of energy-saving in buildings, new energy-saving block masonry with multi-row cores is commonly used. In this paper, from the study of typical bearing capacity of multi hole concrete block masonry of combining multiple rows of holes, holes in the multi block wall masonry capacity test of heat insulation material characteristics. Test results show that, in the process of multi hole masonry brittle failure characteristics, built-in straw block in the insulation at the same time, can improve the compressive strength of masonry; masonry local diffusion mechanism under the action of stress is significant; and offer the engineering measures.
For the time being there are few literatures about study on the seismic performance of concrete hollow block masonry based on the finite element method, left fewer conclusions for reference. According to characteristics of the finite element software, which has strong capability of nonlinear analysis, some key problems are discussed, including the modeling of the concrete hollow block masonry structure, constitutive relations of the materials in block masonry, damage assessment, solution methods, the application of the dead and live loads and the earthquake wave and the seismic performance analysis. The time-history analysis is carried out on three different type walls with openings. Some key factors, such as core columns and ring beams, which have a great influence on the damage pattern and stability of the structure, are discussed. The conclusion from the paper can provide a beneficial reference for in-depth study of the seismic performance of concrete hollow block masonry and the damage patterns.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
