    Abstract: The use of recycled aggregates rather than new aggregates is suggested by the depletion of natural resources and demolition trash. Compared to natural aggregate, recycled aggregate gives concrete less strength. Concrete can be strengthened by adding fiber, such as steel fibers, at a low volumetric proportion. This study aims to determine the concre... Show More

    Abstract: Block infills are usually regarded as non-loadbearing components in buildings, and are frequently neglected in the analysis and design of building structures. The main objective of this study is to perform static nonlinear analysis of hollow concrete block (HCB) infilled reinforced concrete buildings (RC) subjected to a seismic excitation. For this...
