Experimental Investigation on Punching Behavior of Thick Reinforced Concrete Slabs

open access: yesArchives of Civil Engineering, 2013
The results of experimental test of nine thickset reinforced concrete slabs in punching are presented in the this paper. The aim of the tests was verification of the Eurocode EC 2 procedure, by which the ultimate shear stresses vRd,c depend on the ...

Study on Seismic Performance of a Stiffened Steel Plate Shear Wall with Slits

open access: yesShock and Vibration, 2015
To determine the force mechanism for the steel plate shear wall with slits, the pushover analysis method was used in this study. An estimated equation for the lateral bearing capacity which considered the effect of edge stiffener was proposed.

Effect of Load Eccentricity on CRC Structures with Different Slenderness Ratios Subjected to Axial Compression

open access: yesBuildings, 2023
The use of nonmetallic reinforcement in concrete aims at the decrease in material consumption by reducing the component sizes when compared to conventional reinforced concrete structures, which inherently results in very filigree structures.
