Punching shear behavior of reinforced concrete slabs using steel fibers in the mix
HBRC Journal, 2018 One of the major problems of flat slab is the punching shear failure of slab-column connection. This form of failure must be avoided.Fourteen slab-column connections are tested to failure and categorized in two phases.

Load-bearing capacity of integrity reinforcement depending on change of the mechanical parameters of the steel [PDF]
MATEC Web of Conferences, 2020 The paper presents the results of numerical simulations performed on a simplified model of a slab-column connection. The aim of the investigations was to determine the value of the load at which the destruction of such a connection occurs due to a ...

Punching shear of RC slabs exposed to fire: assessment of load-bearing capacity based on European and American provisions. Part 1 – General code requirements [PDF]
Archives of Civil EngineeringSlab-column connection is one of the most critical points in reinforced concrete structures. Punching shear capacity of this connection must be properly determined in both the persistent design situation and the accidental design situation of fire ...

Cyclic Behavior of Reinforced Concrete Slab-Column Connection Using Numerical Simulation
Advances in Civil Engineering, 2022 Nonlinear finite element (FE) simulation was employed to look into the behavior of flat slab-column connections exposed to lateral cyclic loading. The study focused on the effect of drop panel and concrete grade by taking into consideration the element ...

Experimental assessment for non-monolithic slab-column connections
Ain Shams Engineering Journal, 2021 It is common practice to use non-monolithic connections to connect the new flat slabs to the existing columns for upgrading the stories number of the existing buildings, despite the lack of design guidelines for the non-monolithic connection. Therefore, the current study evaluated four different techniques to connect the flat slabs with columns non ...

Conformational Switching of Proteins on Material Surfaces Enabled by Peptide‐Oriented Adsorption
Advanced Functional Materials, EarlyView.Responsive biointerfaces could be achieved using conformationally responsive proteins; however, their interconversion can be lost upon surface adsorption. Herein, we demonstrate that the incorporation a Au binding peptide into calmodulin allows for binding control on Au wherein the protein retains conformational switching. This capability was confirmed
