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‐

Method for determination of optimal geometrical parameters of a unit cell of X-shaped truss cores
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2019 Recently, in order to develop high-strength lightweight core materials of sandwich structures for multi-functional applications, a large number of truss structures have been created, including pyramidal and tetrahedral truss cores.

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 ...

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.

TRUSS STRUCTURES IN CONSTRUCTIONS
Journal of Industrial Design and Engineering Graphics, 2015 The paper presents how truss structures can be used in building different types of spatial constructions. The authors are presenting a documented history of truss structures, through time, from simple to complex structural systems. The presentation starts with the most common and simple structure, the planar truss system, and moves on until the more ...

TRUSS STRUCTURE OPTIMIZATION BASED ON IMPROVED WOLF PACK ALGORITHM [PDF]
, 2019 Aiming at the optimization of truss structure, a wolf pack algorithm based on chaos and improved search strategy was proposed. The mathematical model of truss optimization was constructed, and the classical truss structure was optimized. The results were

Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns
Structural Concrete, EarlyView.Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.

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
