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 ...

On the nonlinear behaviour of reinforced concrete frames

Canadian Journal of Civil Engineering, 1990
An experimental investigation is described in which a large-scale reinforced concrete plane frame is tested to study factors contributing to its nonlinear behaviour under short-term loading conditions. The test results indicate that frame behaviour can be significantly affected by second-order influences such as material nonlinearities, geometric ...

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.

Modified Harmony Search for Optimization of Reinforced Concrete Frames

2017
In this study, harmony search algorithm is modified with several random search stages for optimum design of reinforced concrete frame structures. The structure is subjected to both static and dynamic forces. A detailed optimum design was proposed without grouping the design variables of the frame structure.

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 ...

Inelastic Analysis of Reinforced Concrete Frames

Journal of the Structural Division, 1974
The imposed rotation method for the inelastic analysis of frames rests on the interpretation of the actual bending moment distribution as the superposition of linear elastic moment responses to loads and to unknown plastic rotations regarded as imposed strains.

Seismic Response of Reinforced Concrete Frames

Journal of the Structural Division, 1981
Analytical studies of the elastic and inelastic response of reinforced concrete frames subjected to earthquake motion are presented. The effect of stiffness degradation on the seismic response and in particular on ductility demand is examined. Several single-story frames are analyzed; stiffness degradation significantly increases ductility demand in ...
