This paper presents the application of the harmony search based algorithm to the optimum detailed design of special seismic moment reinforced concrete (RC) frames under earthquake loads based on American Standard specifications. The objective function is selected as the total cost of the frame which includes the cost of concrete, formwork and reinforcing steel for individual members of the fram...

this article presents the application of two algorithms: heuristic big bang-big crunch (hbb-bc) and a heuristic particle swarm ant colony optimization (hpsaco) to discrete optimization of reinforced concrete planar frames subject to combinations of gravity and lateral loads based on aci 318-08 code. the objective function is the total cost of the frame which includes the cost of concrete, formw...

This study proposes a novel artificial intelligence (AI) model to estimate the shear strength of reinforcedconcrete (RC) deep beams. The proposed evolutionary multivariate adaptive regression splines (EMARS) model is a hybrid of multivariate adaptive regression splines (MARS) and artificial bee colony (ABC). In EMARS, MARS addresses learning and curve fitting and ABC implements optimization to ...

To study the performance of UHPFRC continuous deep beams with openings, experimental and numerical investigations have been carried out. The test program included seven in addition to one similar solid beam. variables were ratio transverse reinforcement position, height, width opening. results showed that failure mode two-span depends mainly on position size opening shear span. occurs diagonal ...

Current design codes and specifications allow for part of the bonded flexure tension reinforcement to be distributed over an effective flange width when T-beams' flanges are in tension. This study presents experimental numerical investigation on reinforced concrete flanged section's flexural behavior is laterally distributed. To achieve goals study, analysis using finite element method was cond...

Keruntuhan geser pada balok beton bertulang tanpa tulangan merupakan keruntuhan yang sangat getas. Sejumlah besar penelitian eksperimental mengenai menunjukkan fakta bahwa kegagalan proses kompleks dan adalah efek dari berbagai parameter memberikan pengaruh signifikan, diantaranya kuat tekan (f′c), rasio bentang geser-tinggi efektif (a/d), longitudinal (), tinggi penampang (d). Oleh karena itu,...

In the current manuscript, we aimed to evaluate application of aerated concrete blocks for construction single-family homes in Guayaquil, Ecuador, through a comparison with conventional materials. The design structural elements was carried out according NEC-2015 and ACI 318-14 standards, which 36% reduction dead load structure achieved by using masonry house. With life cycle analysis, quantific...

In the design and assessment of precast concrete beams with a slab cast on top, namely composite beams, engineers still face in practice unsolved shear-related issues, such as contribution to shear strength slab, be considered formulations or influence interface between concretes behaviour. present research, 69 tests were performed monolithic rectangular T-shaped cross-section, without transver...
