Optimizing UHPC Layers to Improve Punching Shear Performance in Concrete Slabs
BuildingsFlat slabs supported by columns without beams are widely used in construction owing to their economy and efficiency. However, brittle punching shear failure at slab–column connections can cause progressive collapse.

Performance of Shear Reinforcement against Punching Shear Loads
International Journal of Engineering and Advanced Technology, 2019 This research targets to maximize the ductility and strength of the reinforced concrete flat slabs. However, to be efficient, the shear reinforcement must be anchored well in the tension and compression zones of the slab. The test results on the slab-column connection models which provided with shear reinforcement are introduced in this study.

Biodegradable Adhesive Systems for Bio‐Integrated Applications
Advanced Science, EarlyView.Biodegradable adhesives provide temporary yet reliable adhesion while degrading into safe, non‐toxic by‐products under physiological or environmental conditions. This review summarizes recent developments in physical and chemical adhesion mechanisms—including hydrogen bonding, catechol chemistry, amine‐carboxyl coupling, and emerging diazirine and urea

Effects of Posttensioning Slippage on 2-Way Spanning Concrete Slabs
Advances in Civil Engineering, 2015 This paper investigates the effect of improper posttensioning of a 2-way spanning concrete slab subject to a central point load. Due to plate slippage alone, the support conditions only offered a 1-way spanning action which could have led to premature ...
