Scrap tire rubber pad (STRP) isolators are made from scrap automobile tires, which expected to be a low-cost material for earthquake-resistant design of low-to-medium-rise buildings in developing countries. This paper describes the seismic vulnerability unbonded STRP (U-STRP) base-isolated masonry building using finite element method. The three-dimensional model U-STRP is placed between foundat...

Abstract Retrofitting thermal insulation to solid masonry walls alters their hygrothermal behaviour, which can be modelled by simulation software. However, such software needs values of key material properties ensure satisfactory results and until now data has not been available for Scottish buildings. This work aims contribute a Scotland-specific dataset use designers working on Thermal conduc...

Damage caused by soils subject to change in volume beneath light structures, particularly low-cost housing units of masonry construction, is unacceptably frequent. It has led the demolition many such within a small fraction their design lifespan. Perhaps most spectacular failure Lerato Park Kimberley, where development was demolished four years. The reason for this examined Stott and Theron (20...

an experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. the first specimen was a reinforced concrete frame with solid-brick infill. the second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. the last specimen was a reinforced concrete frame without any infill. these three specimens were tested by pseudostatic method. di...

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.

1. Abstract Topology optimization is employed to define the geometry of the cross-section of any masonry block that minimizes its thermal transmittance, with the aim of maximizing the thermal insulation of masonry buildings. Constraints on the mechanical properties of the block are also prescribed. The effect of the design constraints on the optimal layout of the blocks is investigated. The the...
