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 ...

Nanoengineered Binetworks in Multifunctional Anionic Block Polymer Mesoblends for Improved Mechanical Properties

Advanced Functional Materials, EarlyView.
Mesoblends consist of a nanostructured polymer into which a second polymer is imbibed with a selective solvent. In this work, a solvent‐templatable pentablock terpolymer possessing a sulfonated midblock is modified with a hydrophilic polymer that is photocrosslinked in situ, yielding a hierarchical binetwork.

Punching shear strength of steel fibre reinforced lightweight concrete slabs. [PDF]

, 1981
One of the problems in slab-column connections is the punching shear failure at over loads. Such failures are sudden and catastrophic, and are undesirable since they do not allow an overall yield mechanism to ...

Experimental Study on Punching Shear Behavior of Ultra-High-Performance Concrete (UHPC) Slabs

Buildings
This study assesses the punching shear characteristics of ultra-high-performance concrete (UHPC) slabs in two phases. The initial phase involved experimental tests to determine the critical thickness differentiating punching shear failure and flexural ...

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Influence of the Distribution and Level of Post-Tensioning Force on the Punching Shear of Flat Slabs

Designs, 2022
Punching shear is the most common failure mechanism of slabs that are supported directly on columns. The slab–column connection is always vulnerable to critical punching shear; thus, it is necessary to investigate the effect of various parameters on the ...

Punching Shear Capacity Analysis of Reinforced Concrete Slab-column Connections [PDF]

Proceedings of the 2015 International Conference on Advanced Engineering Materials and Technology, 2015
In order to solve punching shear strength problem of reinforced concrete slab-column connections, an improved punching shear capacity formula is presented. First, punching shear capacity of reinforced concrete slab-column connections is analyzed. Then, a comparison of punching shear capacity calculation methods is studied based on the codes: GB50010 ...
