Effect of premature loading on punching resistance of reinforced concrete flat slabs

Case Studies in Construction Materials, 2020
Premature loading of reinforced concrete flat slabs in multi storey buildings during construction may occur after shuttering removal and loading slabs earlier than usual to meet project time targets.

Investigation of longitudinal reinforcement contribution in shear punching of reinforced concrete flat slabs without transverse reinforcement [PDF]

MATEC Web of Conferences, 2019
The shear punching of the reinforced concrete slabs is a complex process occurring when considerable force is concentrated on the relatively small area of a column-slab connection. An incorrect assessment of load capacity of slab under the punching shear

Research on the Punching Shear Performance of Steel Grid–UHPC Composite Bridge Decks

Buildings
This study conducted punching shear tests on steel grid–ultra-high-performance concrete (UHPC) composite bridge decks and performed finite element analysis (FEA) to evaluate their punching shear performance. Initially, a comparative analysis is conducted

Reduced area approach for predicting punching shear resistance of biaxial hollow slabs with openings

Results in Engineering, 2023
Due to the inclusion of hollow plastic spheres in bubbled slab systems, the shear resistance is greatly reduced. Also, the existence of the opening in the vicinity of columns takes away part of the concrete responsible for resisting shear forces and ...

Experimental study on the punching–shear performance of reinforced concrete slab‒column joints with various reinforcements and openings

Journal of Asian Architecture and Building Engineering
To elucidate the punching–shear failure mechanism and effect pattern of reinforced concrete (RC) slab–column joints with stirrups and/or openings, punching–shear failure tests were systematically conducted on 11 RC slab–column joint specimens to study ...

Effect of column dimension on the punching shear capacity of concrete slabs reinforced with GFRP bars [PDF]

E3S Web of Conferences
Traditional steel reinforcements are highly susceptible to corrosion affecting their durability and leading to structural weaknesses. The use of GFRP bars offers a corrosion-resistant alternative, potentially extending the lifespan and durability of ...

3D‐Printed Titanium Gyroid Scaffold Structure Integrated With Tough Hybrid Materials for Cartilage Replacement

Advanced Engineering Materials, EarlyView.
This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.

Experimental Investigation on Punching Strength and Deformation Capacity of Shear-Reinforced Slabs [PDF]

ACI Structural Journal, 2012
This paper presents the results of an extensive experimental campaign on 16 flat-slab specimens with and without punching shear reinforcement. The tests aimed to investigate the influence of a set of mechanical and geometrical parameters on the punching shear strength and deformation capacity of flat slabs supported by interior columns.
