The ASTM C1138 standard underwater abrasion test can be considered as the best available experimental tool to qualitatively evaluate the abrasion resistance of concrete surfaces in hydraulic structures. It introduces an accelerated test procedure to

This work primarily aimed to compare the bubble slabs experimentally with solid slabs under the influence of limited repeated four-point loads. Therefore six slab strips were manufactured in the same forms, except the cross-section type. Three were s

In existing buildings, it is common to create openings in slabs due to service supplies. In this case, the mechanical properties of slabs remarkably reduce, and strengthening must be applied. Therefore, this investigation proposed four methods to ret

This paper aims to experimentally and numerically investigate the flexural behavior of laced reinforced concrete moderately deep beams. The study focuses on the influence of the lacing angle (30, 45, and 60°) and the ratio of the tension reinforceme

In the last two decades, the use of voided (bubbled) slabs in constructions has been increased because of several advantages such as light self-weight, cost-saving, and accelerated construction schedules. However, the structural behavior of such slab

A finite element thermal analysis was conducted in this study with the aim of evaluating the influence of the geometrical parameters of steel sections on their thermal response under solar radiation. Four W12 and W24 standard steel beams were investi

The self-compacting concrete (SCC) was invented to overcome the compaction problems in deep sections, owing to its perfect workability characteristics. Steel fibers when used with SCC would affect the required fluidity characteristics but improve its
