Evaluation of cold joint effects on the microstructure and mechanical behavior of three‐dimensional printed concrete specimen

Structural Concrete, EarlyView.
Abstract 3D concrete printing (3DCP) is an automated construction technique that uses an extrusion process to fabricate structures efficiently. However, the layer‐by‐layer process can create interlayer weaknesses, and interruptions during printing can result in cold joints, which can negatively affect the structural behavior.

Contribution of dowel action to interfacial shear transfer in flat joints with unbonded posttensioned bars for precast segmental bridges

Structural Concrete, EarlyView.
Abstract Dry joints are widely used in precast segmental bridge construction because they simplify assembly and accelerate erection. Incorporating fasteners crossing flat dry joints represents an innovative configuration for this type of connection.

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

Structural 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

Structural 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 ...
