چکیده

In this paper, an optimization approach was presented for the flexural strength and stiffness design of reinforced concrete beams. Surrogate modeling based on machine learning applied to predict responses structural system in three-point flexure tests. Three input variables, area steel bars compression zone, tension shear were adopted dataset arranged by Box-Behnken method. The composed thirteen specimens tested under loading at age 28 days both failure load maximum deflection values recorded. Compression tests conducted obtain data analysis numerical modeling. Afterward, finite element performed all using ATENA program verify experimental Subsequently, surrogate models constructed. Finally, supporting factorial method predicted responses. proved be excellent tool optimize beams stiffness. addition, results very good agreement terms type cracking pattern.

Optimum Design of Reinforced Concrete Beams using Teaching- Learning-Based Optimization

Efficiency of reinforced concrete (RC) design can be measured by finding the design with minimum cost within all possible ones that satisfied security conditions. This task is difficult because RC members consisting of two materials; concrete and steel bars with different material properties i.e., compressive and tensile strength, elasticity modulus, and unit material costs. Thus, an additional...

Flexural Testing of High Strength Reinforced Concrete Beams Strengthened with CFRP Sheets

The objective of this study is to investigate the effectiveness of externally bonded CFRP sheets to increase the flexural strength of reinforced high strength concrete (HSC) beams. Four-point bending flexural tests to complete failure on six concrete beams, strengthened with different layouts of CFRP sheets were conducted. Three-dimensional nonlinear finite element (FE) models were adopted by A...

Experimental Investigations on The Flexural Strength of PET Reinforced Concrete

Due to the rapid industrialization taking place globally, the problems generated are acute shortage of construction material and increasing in productivity of wastes. The production and consumption of plastic and the rate at which solid plastic waste (SPW) are created have increased considerably. Plastics constitute 12.3% of total waste produced most of which is from discarded water bottles. Th...

Flexural Strengthening of Deficient Reinforced Concrete Beams with Post-Tensioned Carbon Composites using Finite Element Modelling

The application of external post-tensioned steel bars as an effective way to strengthen an existing bridge has been so far used in many different countries. In recent decades, however, they have been replaced by bars made from Carbon Fiber Reinforced Polymer (CFRP), as a material with high tensile strength and corrosion resistance, to address several concerns with steel bars such as their appli...
