Through numerical simulation, the blast-resistant performance of spray polyurea elastomer (SPUA) retrofitted concrete masonry unit (CMU) infill walls under far-range blast loading was studied. From an engineering perspective, effects boundary conditions and thickness a SPUA layer on enhancing resistance are discussed, SPUA-retrofitted grouted CMU compared. It is concluded that constraint anchor...

This work concerns an assessment of the behavior of infilled frames. The feasibility of possible immediate implementation of some recent developments both in analysis and design of infilled frames for practical design is investigated. It is now widely recognized that masonry infill panels used in reinforced concrete (R/C) frame structures, significantly enhance both the stiffness and the streng...

Open Ground Storey buildings (OGS) are commonly constructed in the UAE, since these has some functional advantage as parking, shop etc. However, they can be a hazard during an earthquake. In this study, real building located Al Muraqqabatm Dubai is chosen. This type of OGS coupled with shearwall. To understand behaviour and strength non-linear Static Analysis (Pushover Analysis) carried out to ...

Introduction: The received dose to the surface of tumor bed is one of the main issues in beast intraopeative radiotherapy (IORT). Totally, the administered dose to the surface is usually lower than that of radiotherapy reference point (distal end of tumor bed). Employing a buildup bolus can effectively increase the surface dose and therefore, eliminate such created cold points ...

Masonry infill walls are often used as non-structural elements. According to the past structural failure, ignorance of interaction between infill walls and enclosed frame may lead to the different seismic response for non-ductile building frames. The main contribution of this paper is to analytically investigate the behavior of reinforced concrete with masonry infill panels as participating str...

4 FRP strengthening systems for infill masonry walls are typically designed to resist flexural stresses due to out-of5 plane pressure. Previous research has shown that there are potential premature failure mechanisms due to shear 6 sliding of the infill, which could reduce the effectiveness of the strengthening system. Current design guidelines for 7 strengthening of masonry walls with fiber-re...

BACKGROUND Artificial sports fields are increasingly being used for sports. Recycled rubber from automotive and truck scrap rubber tires are used as an infill material for football grounds. There are concerns that football players may be at risk due to exposure from released compounds from rubber infill. Compounds from crumb infill may be inhaled and dermal exposure may occur. A study was perfo...
