Numerical Modelling of Timber Braced Frame Masonry Structures (Dhajji Dewari)
This paper presents numerical modeling technique for Dhajji-Dewari structures (timber-braced rubble stone masonry), and its application for the evaluation of in-plane force-deformation capacity of Dhajji wall panels of different configuration of bracings. Dhajji structures are mainly composed of vertical and horizontal timber posts and braced using diagonal bracings and horizontal studs. Wall o...
متن کاملModeling of FRP-Strengthened Infill Masonry Structures
This paper presents an analytical approach to describe the behavior and mode of failure of infill masonry structures strengthened with fiber-reinforced polymer (FRP) materials. The approach is used to simulate the response of strengthened infill masonry walls under the effect of out-of-plane uniformly distributed pressure simulating wind pressure. The approach includes a finite element analysis...
متن کاملModal Analysis of Masonry Structures
This paper presents a new numerical tool for evaluating the vibration frequencies and mode shapes of masonry buildings in the presence of cracks. The algorithm has been implemented within the NOSA-ITACA code, which models masonry as a nonlinear elastic material with zero tensile strength. Some case studies are reported, and the differences between linear and nonlinear behaviour highlighted.
متن کاملNew Frontiers on Seismic Modeling of Masonry Structures
An accurate evaluation of the non-linear behavior of masonry structural elements in existing buildings still represents a complex issue that rigorously requires non-linear finite element strategies difficult to apply to real large structures. Nevertheless, for the static and seismic assessment of existing structures, involving the contribution of masonry materials, engineers need reliable and e...
متن کاملAnalysis of coupled heat and moisture transfer in masonry structures
Evaluation of effective or macroscopic coefficients of thermal conductivity under coupled heat and moisture transfer is presented. The paper first gives a detailed summary on the solution of a simple steady state heat conduction problem with an emphasis on various types of boundary conditions applied to the representative volume element – a periodic unit cell. Since the results essentially sugg...
