Optimization of Reinforced Concrete Frames

Journal of Structural Engineering, 1997
The optimization of three-dimensional (3D) reinforced concrete frames is discussed. The validity of the assumption that optimum concrete-section dimensions are insensitive to the number, diameter, and longitudinal distribution (topology) of reinforcing bars is examined.

Nonlinear Model for Plane Reinforced Concrete Frames

Civil-Comp Proceedings, 2009
A nonlinear finite element model is proposed in order to analyse reinforced concrete frames. The finite element adopted is constituted by an elastic beam, having axial and flexural stiffness, connected to nodes by means of two potential generalised plastic hinges, having rigid-perfectly plastic behaviour. Activation of plastic hinges occurs as internal

Seismic Damage in Reinforced Concrete Frames

Journal of the Structural Division, 1981
Seismic damage in reinforced concrete frames is predicted by analytical methods. Analytical models are developed which can reproduce the behavior of reinforced concrete members under cyclic loads. Accuracy of the analytical models is checked by considering a set of quasi-static cyclic load tests, and the models are found to be sufficiently accurate ...

Moment redistribution in reinforced concrete frames

Journal of the Chinese Institute of Engineers, 1986
Abstract The nonlinear behavior of reinforced concrete frames with sidesway is governed by two effects: first, the nonlinearity of materials due to cracking and the plastic behavior of materials, and second, the nonlinearity of geometry caused by the second‐order deformation.

Reinforced Concrete Frames in Fire Environments

Journal of the Structural Division, 1977
In modeling the fire response of reinforced concrete frame structures, the heat flow problem was separated from the structural analysis and two computer programs were written for solving the separate problems. Both programs account for the temperature dependence of the thermal and mechanical properties of materials; the structural analysis accounts for

Lateral Stiffness of Plane Reinforced Concrete Frame

Civil-Comp Proceedings, 1997
Abstract This paper discusses applying a nonlinear analytical model to reinforced concrete frames for computing its response to lateral loading. The nonlinear analysis takes into effect the material and geometric nonlinearities. From lateral loading and lateral drift, lateral stiffness can be obtained.

Seismic Overstrength in Reinforced Concrete Frames

Journal of Structural Engineering, 1995
Seismic overstrength of multistory reinforced concrete frames has been assessed by means of nonlinear pseudostatic analysis on four-bay, three-, six-, and nine-story frames designed for seismic zones I to V as per Indian codes. In pseudostatic analysis, the lateral force profile corresponding to the first mode of elastic vibration is applied ...

Reinforced Concrete Frames under Distant Blast

Key Engineering Materials, 2017
The article deals with the field tests of UHPFRC frames loaded by distant detonation of 50 kg of TNT and also by direct explosion of 120mm mortar shell. The paper analyses the results obtained from ultrasound diagnostics that was made before and after the explosion.

Design of Reinforced Concrete Infilled Frames

Journal of Structural Engineering, 2014
AbstractThe work presented in this paper aimed to evaluate the diagonal strut model for the design of reinforced concrete (RC) infilled frames, already broadly used as a design tool in the case of masonry infilled RC frames. The assumptions on which the strut model provisions in codes are based are reviewed.
