Natural rock joints infilled with soil materials may show a reduced shear strength, which influences rock mass stability. The aim of this paper is to experimentally investigate the shear behaviour of infilled rock joints, taking into account joint surface characteristics and the properties of the joint and infill materials. A new model for predicting the shear strength of infilled joints is pre...

As a common enclosure structure, masonry walls are widely used in various types of buildings. However, due to the weak out-of-plane resistance and generally brittle properties materials for blocks, they highly susceptible collapse under blast loads produce high-speed splash fragments, which seriously threatens safety personnel equipment inside In this paper, based on existing tests, refined num...

Introduction: Seismic damage affecting the non-structural components of buildings (such as infills) can significantly impact expected economic losses over a structure’s service life. Recently, autoclaved aerated concrete (AAC) infills have gained attention in construction industry due to their light weight, energy efficiency, and durability. Methods: This study investigates out-of-plane behavio...

the rapid and sprawl development city in recent decades has created many problems for cities and causing instability in urban environments. the late twentieth century these problems caused a revision in urban planning models and introduction of new models such as the infill development. studies show that third world countries like iran are faced with sprawl development model and should take the...

Abstract The Vettore–Bove normal fault system in central Italy ruptured during the 2016 M W 6.5 Norcia earthquake causing extensive surface faulting. At Pian Grande di Castelluccio hanging wall basin, along southern section of mainshock, we performed a high‐resolution seismic reflection/refraction experiment aimed at (a) imaging shallow pattern system, and (b) reconstructing architecture contin...

Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...

the present study is concerned with the simultaneous optimization of the size of components and the arrangement of connections for performance-based seismic design of low-rise spsws. design variables include the size of beams and columns, the thickness of the infill panels, the type of each beam-to-column connection and the type of each infill-to-boundary frame connection. the objective functio...

The influence of chained masonry walls, which represents a special case infill without gap, on the seismic response reinforced concrete buildings is extremely important due to their wide use in this type building. We can consider period building as key parameter study influence. In article, we had carried out comparative several 2D models multi-storey with brick wall using spectrum method ETABS...

This numerical analysis has discussed the behaviour of frame structure with eccentric infill wall opening modelled shell and strut elements. In beginning, validation models were created by following laboratory tests results. Then, a simple one-storey an was varying ratios taking angle formed to obtain equation for width that corresponds element model angles variation. The then applied 3-storey ...
