A hybrid topology optimization method applied to reinforced concrete structures using polygonal finite elements [PDF]

Revista IBRACON de Estruturas e Materiais, 2023
This work introduces a new alternative to obtain strut-and-tie models using the hybrid topology optimization method, which is already proposed in the technical literature and is refined here to use polygonal finite elements and accelerate the solution of

Proposition and analysis of strut and tie models for short corbels from techniques of topology optimization

Revista IBRACON de Estruturas e Materiais, 2021
Reinforced concrete short corbels are components characterized to represent typical conditions of geometrical and static discontinuity. In general, the classical bending theory is not valid for their design.

Strut-and-tie model based on crack band theory for deep beams [PDF]

, 2010
yesA simplified strut-and-tie model including size effect based on the crack band theory is proposed to evaluate the shear capacity of deep beams. Concrete struts are idealized as uniformly tapered prismatic members with a stress relief strip whereas ...

Modified interactive strut-and-tie model for shear strength prediction of RC corbels

Engineering and Applied Science Research, 2019
On the basis of the modified Kupfer and Gerstle’s biaxial failure criterion ofconcrete, amodified interactive strut-and-tie model (MISTM) to predict the nominal shear strength of RC corbels was derived and is proposed in this paper.
