Performane Assessment of Unreinforced Masonry Low-Rise Building Composed of Limestone Bricks Under Seismic Loading

摘要

This paper demonstrates the analytical investigations of the nonlinear behavior of entirely limestone unreinforced maso nry structure (URM) co mposed of barrel vaults rested on wall bearing under seismic loading where the nonlinearity mean the ultimate capacity. Usually, linear analysis is conducted for simplifying analysis and design of masonry structures by using load and strength factors. However, such simplification might underestimate the structural capacity of these constructions in many cases, and thus the nonlinear analysis gives better description for the actual behavior and capacity of the structure. The finite Element Program (Abaqus) was used to analysis the proposed limestone URM building.
