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 ...

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.

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.

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.

Metaheuristic Optimization of Reinforced Concrete Frames

2020
In this chapter, an optimum design methodology for reinforced concrete (RC) frames are presented. In the optimum design of frames, both beams and columns are optimized. In addition to that, internal forces can be modified according to rigidity of members for statically indetermined frames.

Limit Design of Reinforced Concrete Frames

Journal of the Structural Division, 1968
A limit design method is presented in which load factors against all possible modes of structural collapse and against yield of all critical sections are prescribed. The design plastic moments are some fractions of the elastic envelope moments under the specified ultimate load.

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 ...

Rehabilitation of reinforced concrete frames by reinforced concrete infill walls

2020
ABSTRACT Seismic rehabilitation of the existing reinforced concrete framed buildings is an important engineering problem. The main aim of the rehabilitation process is to upgrade the stiffness, strength of the structure to the required level and to reduce the lateral drift below an acceptable limit. To satisfy all these requirements, introducing infill
