Structural Concrete, EarlyView.Abstract The structural role of precast concrete walls with openings is often overlooked in design practice due to concerns about reduced stiffness, stress concentration, cracking around openings, and potential unexpected failure modes under seismic loading.

Structural Concrete, EarlyView.Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

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‐

Structural Concrete, EarlyView.Abstract In precast concrete structures, optimizing the design of corbels by considering the contributions of secondary reinforcement elements can significantly improve construction economy, especially when corbels are repeated multiple times. This paper proposes a strut‐and‐tie model for reinforced concrete corbels subjected to vertical and/or ...

Non-linear analysis of plane steel prestressed truss in fire
Journal of Civil Engineering and Management, 2002 The concept of analysis of 2-D static loaded prestressed steel trusses till failure during fire using a modified method of forces is presented. Failure of steel trusses in fire is based on the criterion of stresses. Behaviour of steel is described by non-

Effect of Truss Number on the Dynamic Response of Truss
DEStech Transactions on Computer Science and Engineering, 2019 The safety of truss is determined by dynamic response of truss during the engineering application. Truss number is an important parameter for the engineering application of truss, which is related with the economy and convenience. The effect of truss number on the dynamic response of truss can be analyzed by means of commercial finite element software.

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.
