This study aims to develop artificial neural networks (ANNs)-based forward Lagrange optimizing ductile doubly reinforced concrete (RC) beams. Cost (CIb) of materials and manufacture were established as an objective function, which is minimized considering constraints according engineer’s needs. Large datasets 100,000 used derive AI-based function for cost (CIb, minimizing RC beams) a input para...

This paper deals with the effect of steel fiber amounts and interaction between amount stirrup ratio on shear behavior capacity reinforced concrete (RC) deep beams fibers. The experimental program was carried out twelve different (0, 30, 40, 65 kg/m3) ratios (0.1, 0.15, 0.25%). test results have shown that use fibers increased resistance (up to 55%), reduced crack width 11 times) deflection 57%...

This study investigated the response of reinforced concrete (RC) slabs in building structures to internal explosions. The performances of two slabs designed in accordance with the protective structural design and conventional gravity design approaches were evaluated in terms of midspan displacements, support rotations, and damage patterns. Data from available slab blast experiments in the open ...

Externally bonded carbon-epoxy fiber-reinforced polymers (CFRPs) have been widely used to restore or increase the capacities of reinforced concrete beams (Meier et al., 1992; Neale and Labossière, 1997; Varastehpour and Hamelin, 1997). A typical reinforced concrete bridge deck may experience up to 7x10 stress cycles during the course of a 120year life span (Barnes and Mays, 1999), while an over...

Fiber reinforced polymer materials are continuing to show great promise for using strengthening reinforced concrete structures. These materials are an excellent option for use as external reinforcing, because of their light weight, resistant to corrosion and high strength. The main aim of this study is to investigate the flexural characteristic of RC beams using GFRP sheets and strips. This pap...
