ANALYSIS OF CONCRETE BEAMS WITH CIRCULAR WEB OPENINGS USING STRUT-AND-TIE MODELS
Malaysian Journal of Civil Engineering, 2018 This study examines the strut-and-tie model for the analysis of reinforced concrete beams that contain geometric discontinuities in the form of a transverse circular opening in the web.

Optimized Design of Anchor Plates for 2200 MPa-Class Prestressing Anchorage Zones
BuildingsThe strength of prestressed steel strands has developed towards high strength, increasing from 1860 MPa to over 2200 MPa. The stress in the prestressed anchorage zone is more concentrated and complex, and the anchor plates for dispersed loads need to be ...

Analysis of nodal stress on reinforced concrete two-pile caps supported on steel piles
Revista IBRACON de Estruturas e Materiais, 2020 : Reinforced concrete pile caps may be designed trough plastic models (strut and tie model) or models based on bending theory. The formulae available for verifying the stress is based on caps supported on concrete piles, with few studies about the stress

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‐

Improvement and Application of the Softened Strut-and-Tie Model
IOP Conference Series: Materials Science and Engineering, 2017 Previous experimental researches indicate that reinforced concrete beam-column joints play an important role in the mechanical properties of moment resisting frame structures, so as to require proper design. The aims of this paper are to predict the joint carrying capacity and cracks development theoretically.

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 ...

Development of strut and tie models for simply supported deep beams using topology optimization [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2008 Generally, structural members can be broadly divided into two regions, namely B, or Bernoulli regions, where the strain distributions are linear and D, or Disturbed regions, where the strain distributions are nonlinear While well defined theories are ...

Application of strut-and-tie model on eccentric columns
Mechanics, 2011 The popular strut-and-tie model is currently de fined by EC2 as a standard tool for simple structures. This paper explores the possibility of application of the strut and-tie model on more complex structures, specifically on the eccentric columns. Comparison with full numerical simulation shows that the strut-and-tie model can correctly predict the ...

Kinematics‐based model for shear capacity assessment of unreinforced interior beam–column joints
Structural Concrete, EarlyView.Abstract This study presents a kinematics‐based model for assessing the shear strength of reinforced concrete interior beam–column joints without transverse reinforcement. The proposed framework is built on first principles—kinematics, equilibrium, and constitutive relations—and explicitly models discrete cracks by introducing kinematic parameters such

Budownictwo i Architektura, 2013 Although Strut and Tie models are often used in practical design due to their apparent concept based on truss analysis, the creation of a model consistent with behaviour of the real structure is not an easy task.
