Shear Lag Effect Analysis of GFRP Composite Truss Web Girder Bridge

Buildings
To clarify the shear lag effect and flexural performance of glass fiber-reinforced polymer (GFRP) composite truss web girder bridges and verify the feasibility of substituting steel truss webs with GFRP members, a refined finite element (FE) model was ...

Reverse engineering strut‐and‐tie models for assessing reinforced concrete structures

Structural Concrete, EarlyView.
Abstract Strut‐and‐tie models enable the design of reinforced concrete structures with static or geometrical discontinuities, providing interpretability and control over the load path. These models are valuable for designing discontinuity regions of new structures and for validating nonlinear finite‐element analysis results. However, developing a strut‐

Study on elastic deformation calculation method of a composite-metal hybrid assembling stringed truss bridge [PDF]

MATEC Web of Conferences, 2019
A composite-metal hybrid assembling stringed truss bridge which based on pre-tightened tooth connection can make full use of the strength of the FRP fiber in the direction of the fiber, and is of higher bearing capacity than the FRP truss bridges with ...

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

Structural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Inelastic Displacement Ratio Approach for Analyzing the Vertical Elasto-plastic Seismic Responses of Steel Beam Bridges

Taiyuan Ligong Daxue xuebao, 2021
The inelastic deformation of a steel beam bridge under vertical seismic actions would accumulate in the “downward” side, whereas in the “upward” side, the structure keeps elastic. An un-symmetric hysteretic model was established for the steel beam bridge

Influence of shear reinforcement detailing on the shear capacity of reinforced concrete beams

Structural Concrete, EarlyView.
Abstract Alternative shear reinforcement layouts that do not fully enclose the longitudinal tensile reinforcement can significantly improve the constructability of reinforced concrete (RC) members. However, their influence on shear transfer mechanisms is not yet fully understood. To address this gap, an experimental program comprising 10 shear tests on

Experimental Analysis of Static and Dynamic Performance for Continuous Warren Truss Steel Railway Bridge in Heavy Haul Railway

Modelling and Simulation in Engineering
Continuous Warren truss steel railway bridges are one of the main forms of railway bridges. Due to the deterioration of materials and the long-term effect of loads, the bridges will inevitably experience performance degradation, which may lead to the ...

Linear and Nonlinear Performance Evaluation of Composite Space Truss Decks in Cable-Stayed Bridges: Suez Canal Bridge Case Study

Infrastructures
This study investigates the structural performance of a novel composite space truss deck system as an alternative to the conventional steel box girder in cable-stayed bridges. Using the Suez Canal Bridge as a benchmark, comprehensive linear and nonlinear
