Experimental assessment of column rectangularity in flat‐slab slab–column connections

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents an experimental investigation of the punching shear behavior of seven 3.00 m × 3.00 m × 0.20 m flat slabs without shear reinforcement, supported by internal rectangular columns. The column side lengths were varied to obtain aspect ratios, cmax/cmin, from 1.67 to 4.00, while the flexural reinforcement and overall slab ...

Strong ground motion and structural damage in the 2023 Kahramanmaraş earthquakes: A comparative case study of numerical predictions and field observations

open access: yesStructural Concrete, EarlyView.
Abstract On February 6, 2023, southeastern Türkiye was struck by two catastrophic earthquakes (Mw: 7.7 and Mw: 7.6) along the East Anatolian Fault Zone, causing extensive structural failures and significant loss of life. This study evaluates the seismotectonic characteristics of the sequence, analyzes strong ground motion data against the Turkish ...

High temperature fracture behavior and damage evolution of recycled aggregate concrete produced from metakaolin modified parent concrete

open access: yesStructural Concrete, EarlyView.
Abstract The increasing use of recycled aggregate concrete (RAC) offers significant environmental benefits by reducing construction and demolition waste; however, its fracture performance and damage evolution under elevated temperatures remain insufficiently understood, particularly when recycled aggregates are derived from metakaolin modified parent ...

Behavior of exterior beam‐column joint reinforced with shape memory alloy

open access: yesStructural Concrete, EarlyView.
Abstract Beam‐column joints are critical regions in moment‐resisting frames and are particularly susceptible to severe stress concentrations and reinforcement congestion. Conventional design typically relies on dense transverse reinforcement to improve joint performance, resulting in construction difficulties and reinforcement congestion.

Flexural performance of FRP-strengthened concrete beams: A review

open access: yesMuthanna Journal of Engineering and Technology
Performance of FRP-strengthened beams in flexure is critical most recently in the field of concrete structural engineering over possible improvements of strength, ductility, and durability of concrete structures. This paper critically reviews the recent

Near‐field blast behavior of ultra‐high‐performance concrete slabs: Parametric analysis and calibration of the UFC‐3‐340 predictive model

open access: yesStructural Concrete, EarlyView.
Abstract Blast loads impose extreme, short‐duration pressures that can cause severe structural damage and compromise safety, a crucial aspect in critical infrastructure, including nuclear facilities. Whereas ultra‐high‐performance concrete (UHPC) offers superior blast resistance compared to conventional concrete (CC) and high‐performance concrete (HPC),

Strengthening of punching shear of flat slab–column connections through hybrid near‐surface mounted and externally bonded systems: Experimental, numerical, and analytical study

open access: yesStructural Concrete, EarlyView.
Abstract Slab–column connections are vulnerable to punching shear, particularly when flexural cracking reduces the effective depth. This study proposes a sustainable dual‐strengthening system to enhance punching resistance and combined flexural–punching performance.
