“…According to Wahab and Lawal (2011), many tools used by bricklayers include; trowels, brick hammers, chisels, levels, plumbs, and measuring squares, whereby unskilled workers will assist the bricklayer in doing the heavy work such as carrying materials and mixing mortars. • Painters: According to Ali (2016), painters and decorators are often the last line of construction labour to finish a project before the tenants occupy the structure.…”

“…Whether foreign labours coming to Malaysia are skilled or not, it can also trigger several domestic cases that affect individuals or countries if not encourage the locals to involve in the construction industry then reduce the upcoming of foreign labour. Noh et al (2016) reported that many of cases crimes are related to foreign and the people who involve in crime cases most of them are illegal immigrants and foreign labours. Foreign labour has caused several problems in Malaysian companies in the construction industry productivity.…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

“…These composite structures are also referred to as infilled frames and have increased lateral stiffness than structures that have bare frames. In the past six decades, extensive experimental and numerical research has been conducted to understand the combined behaviour of infilled frames, but most of these scholars investigated the behaviour and capacity of masonry infills built inside concrete or steel frames (Mehrabi et al, 1996;Chen and Liu, 2016;Margiacchi et al, 2016;Repapis and Zeris, 2019). Only a few researchers investigated the response of steel frames connected with infill RC walls (Makino et al, 1980;Saari et al, 2004;INNO-HYCO, 2015;Vogiatzis and Avdelas, 2018;Pallarés et al, 2020).…”

Behaviour and capacity of cross-laminated timber (CLT) infills built inside steel frames have been given increasing research attention in recent years. It is widely accepted that when the CLT wall panel is built in tight contact with the bounding steel frame to participate in the load sharing, its inherently large in-plane stiffness will attract additional forces to the frame area and change the behaviour of the hybrid system. If not designed properly, the structural integrity of both the infill and the frame will be compromised. It is thus crucial to accurately evaluate the contribution of the infill CLT wall panel to the stiffness and strength of the hybrid system. To that end, a finite element study was performed to investigate the frame-wall interaction effect on the behaviour of hybrid systems. The lateral stiffness, lateral load capacities and hysteretic characteristics of the hybrid systems with frictional and connected interfaces were investigated. The load-sharing effect between the CLT wall and the steel frame was studied. The numerical results showed that the connected models were very effective as the infill absorbed a substantial part of the lateral load, during the initial stages of loading.

“…Ravichandran and Klingner found that the different strengths caused by different infill material types and thicknesses could change the pushover failure mechanism of infilled MRFs. Kaushik et al, Karayannis et al, and Margiacchi et al analyzed the soft‐story collapse mechanism of the infilled MRFs caused by the open story. However, few studies have paid attention to how the addition of the infills affects the seismic behavior of SC‐MRFs.…”

Summary Steel self‐centering moment resisting frames (SC‐MRFs) have been validated experimentally as resilient structural systems, mainly highlighting the minimized residual drift responses but are prone to suffering high‐mode effects. In this paper, the influence of infill configurations on seismic responses of steel SC‐MRFs was first analyzed. A comparison of the previous experimental results was conducted to investigate the effect of infills on the residual drift of steel frames. In the numerical simulation, the infills were modeled as the equivalent strut diagonals, and the force–displacement of the infills was modeled using the combination of Elastic‐No Tension Material and Hysteretic Material offered by the OpenSees program. The seismic analyses of 3‐ and 9‐story SC‐MRFs with and without infills were carried out to analyze the effects of infills on the residual drift responses and high‐mode contribution under the selected ground motions. Finally, the different infill types and infill irregularities on the seismic responses were investigated to obtain general conclusions. The plastic deformations of columns and infills are also compared in the different cases of infill configurations. The results reveal that all infilled cases experience reduced peak‐story drift and force demands at the upper stories.
