TL;DR: In this article, a method for improving the punching shear strength and behavior of voided slabs by employing steel sheets was presented, and the results revealed that significant losses were recorded in the strength, stiffness, ductility and energy absorption of the voided slab without sheets compared with the reference one.

TL;DR: In this paper, an experimental investigation was implemented for evaluating the behavior of reinforced self-compacting hollow columns after heating to 600 ˚C. The test results revealed that the ultimate load, stiffness, and toughness of columns were reduced after heating and then cooling, whereas the ductility was found to be improved.

TL;DR: In this article, the flexural behavior of reinforced concrete moderately deep beams is investigated and the influence of the lacing angle (30, 45, and 60°) and the ratio of the tension reinforcement (0.33, 1.13, and 2.01%).

TL;DR: In this paper, the authors compared the bubble slabs experimentally with solid slabs under the influence of limited repeated four-point loads, and the results showed that the balls' presence made slabs failed abruptly due to shear mode regardless of the a/d.

TL;DR: In this article, mild steel plates were used as a vertical web reinforcement to improve the behavior of RC deep beams under four-point load with a ratio of shear span to an effective depth ranging from 0.75 to 1.5.
