Performance-based Optimization of Strut-and-tie Models in Reinforced Concrete Beam-column Connections
This paper presents the performance-based optimization of strut-and-tie models in reinforced concrete beam-column connections. The performance-based optimization (PBO) technique is employed to investigate optimal strut-and-tie models in reinforced concrete beam-column connections. Developing strut-and-tie models in reinforced concrete beam-column connections is treated as a topology optimizatio...
متن کاملTopology Optimization of Strut-and-Tie Models in Non-Flexural Reinforced Concrete Members
This paper deals with the topology optimization of strut-and-tie models in non-flexural reinforced concrete members by using the Evolutionary Structural Optimization (ESO) method for plane stress continuum structures with displacement constraints. By means of systematically removing elements that have less contribution to the stiffness from the discritized concrete member, the actual load paths...
متن کاملRefinement of Strut-and-Tie Model for Reinforced Concrete Deep Beams
Deep beams are commonly used in tall buildings, offshore structures, and foundations. According to many codes and standards, strut-and-tie model (STM) is recommended as a rational approach for deep beam analyses. This research focuses on the STM recommended by ACI 318-11 and AASHTO LRFD and uses experimental results to modify the strut effectiveness factor in STM for reinforced concrete (RC) de...
متن کاملEstimating Residual Service Life of Deteriorated Reinforced Concrete Structures
Evaluating present condition of reinforced concrete (RC) structures is necessary for planning future maintenance and estimating residual service life of structures. A ten point (0-9) condition rating system is proposed for obtaining present condition of RC structures based on the measured values of concrete cover, carbonation depth and chloride concentration at rebar depth through in-situ tests...
متن کاملStrut Deformation in CFRP-Strengthened Reinforced Concrete Deep Beams
Strut-and-tie model (STM) method evolved as one of the most useful designs for shear critical structures and discontinuity regions (D-regions). It provides widespread applications in the design of deep beams as recommended by many codes. The estimation of bottle-shaped strut dimensions, as a main constituent of STM, is essential in design calculations. The application of carbon fibre reinforced...
