A beam-column element based on the Euler-Bernoulli beam theory is researched for nonlinear dynamic analysis of reinforced concrete (RC) structural element. Stiffness matrix of this element is obtained by using rigidity method. A solution technique that included nonlinear dynamic substructure procedure is developed for dynamic analyses of RC frames. A predicted-corrected form of the Bossak-α met...

The present study addresses optimal design of reinforced concrete (RC) columns based on equivalent equations considering deformability regulations of ACI318-14 under axial force and uniaxial bending moment. This study contrary to common approaches working with trial and error approach in design, at first presents an exact solution for intensity of longitudinal reinforcement in column section by...

In this present study, experimental work was conducted to study the effectiveness of newly innovated steel-CFRP composite (CFRP laminates sandwiched between two steel strips) as stirrups. A total numbers of eight concrete beams were tested under four point loads. Each beam measured 1600 mm long, 160mm width and 240 mm depth. The beams were reinforced with different shear reinforcements; one wit...

ABSTRACT: Several reinforced concrete deep beams with different L/D ratios (1.5, 1.6, 1.71) were cast and tested in order to investigate the strain distribution pattern at mid-section of the beam. This paper describes analysis of deep beams subjected to two point loading with three different L/D ratios (1.5, 1.6, 1.71) using Non-linear Finite element method (ANSYS 9.0 software). In ANSYS 9.0 so...

Seismic pressures on a reinforced concrete moment-resisting structure are known to create critical and essential regions at the beam-column joints. Beam-column junctions microcosm of whole structure, therefore brittle behavior these points predicts action. Ductile joints ductile Under influence seismic forces, between RC beams columns exposed high shear stresses. Learn more about performance fi...

The present Experimental investigation is to study the Impact Resistance of the Fly ash concrete reinforced with steel fibers. The concrete composite comprises of steel fibers in different percentages and partial replacement of cement in different proportions. Steel fibers varied from 0%, 0.5%, 1% and 1.5% by weight of cement and replacement of fly ash varied from 0%, 10%, 20%, 30% and 40% by w...

Reinforced concrete (RC) elements lose their structural strength by exposing to fire as the mechanical properties of reinforcing steel and deteriorate due heat. This study provides an understanding behavior three elements: beam, column, slab at high temperatures using a finite element (FE) modelling produced in ABAQUS, well potential retrofitting these Slurry Infiltrated Fiber Concrete (SIFCON)...

To detect human survivors trapped in buildings after earthquakes by using structure-borne sound it is necessary to have knowledge of vibration transmission collapsed and fragmented reinforced-concrete buildings. In this paper, statistical energy analysis (SEA) considered for modelling seismically damaged, reinforced concrete, beam-to-column junctions where the connection between beam column mad...

Using a genetic algorithm owing to high nonlinearity of constraints, this paper first works on the optimal design of two-span continuous singly reinforced concrete beams. Given conditions are the span, dead and live loads, compressive strength of concrete and yield strength of steel; design variables are the width and effective depth of the continuous beam and steel ratios for positive and nega...
