Flexural Behavior of Pultruded GFRP–Concrete Composite Beams Strengthened with GFRP Stiffeners

Fibers
The utilization and incorporation of glass fiber-reinforced plastics (GFRP) in structural applications and architectural constructions are progressively gaining prominence. Therefore, this paper experimentally and numerically investigates the use of GFRP

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Numerical research on anti‐dislocation measures design of deep‐buried tunnels in an anisotropic rock mass area

Deep Underground Science and Engineering, EarlyView.
This paper conducts a numerical simulation study on the construction of a deep‐buried tunnel in an anisotropic stratum area. A statistical analysis of the effects of two anti‐faulting design measures, namely, a conventional design and an articulated design, is carried out, and the results demonstrate the effectiveness of the anti‐faulting structures ...

Prediction of punching shear capacities of two-way concrete slabs reinforced with FRP bars

HBRC Journal, 2013
Where corrosion of steel reinforcement is a concern, fiber-reinforced polymer (FRP) reinforcing bar or grid reinforcement provides an alternative reinforcement for concrete flat slabs.

Sensitivity of 3D Base‐Isolated Buildings to Individual Isolator Variability

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Variability in elastomeric isolators arises from differences in rubber formulation and curing, leading to noticeable changes in stiffness and damping among nominally identical bearings. While most previous studies have examined global isolator variability associated with environmental or aging effects, individual isolator variability has ...

Experimental Study on Shear Resistance of Existing Prestressed Concrete Hollow Slabs

Zhongwai Gonglu
Prestressed concrete hollow slabs are widely used in small- and medium-sized span highway bridges in China. With the increase in load ratings, many hollow slab bridges built in early periods fail to meet the current specifications for shear bearing ...

Weak‐Story Mitigation and Drift Redistribution in Moment‐Resisting Frames Using Stepping Rocking Walls

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study investigates the seismic response of moment‐resisting frames retrofitted with a stepping rocking wall, with emphasis on weak‐story mitigation and residual drift reduction under both ordinary and pulse‐like ground motions. Nonlinear response‐history analyses are conducted on 9‐story and 20‐story SAC Los Angeles frames.

Finite Element Analysis of Concrete Bridge Slabs Reinforced with Fiber Reinforced Polymer Bars

The Journal of Engineering Research, 2014
Due to their non-corrosive nature, high strength and light weight, fiber reinforced polymers (FRP) are being widely used as reinforcement in concrete bridges, especially those in harsh environments.

Punching Behavior Of Self-Compacting Concrete Slabs Incorporating Coarse Recycled Concrete Aggregates

Wasit Journal of Engineering Sciences, 2020
This paper presents an experimental investigation on the effects of incorporating coarse recycled concrete aggregates (RCA) on the punching and flexural behaviour of reinforced concrete two-way slabs.

Effects of Wall‐to‐Floor Interactions on Seismic Response of Platform‐Type CLT Buildings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Platform‐type cross‐laminated timber (CLT) buildings feature discontinuous wall segments supported by CLT floors. In practice, CLT floors are often treated as rigid diaphragm, yet the wall‐to‐floor interactions (WFIs) associated with flexibility of floors remain insufficiently investigated during seismic performance assessment.
