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.

Reliability Analysis of Reinforced Concrete Frames

Journal of Structural Engineering, 1987
In the case of reinforced concrete frames, full moment redistribution may not take place, and any critical regions may fail because of insufficient rotation capacity before a collapse mechanism is formed. Considering the limited rotation capacity of concrete sections, a method is developed to verify and analyze the identified dominant mechanisms that ...

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 ...

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.

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

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.

Limit Analysis of a Reinforced Concrete Frame

ACI Journal Proceedings, 1971
THIS PAPER IS PRIMARILY CONCERNED WITH A TEST TO FAILURE OF A VERY SMALL-SCALE MODEL OF A REINFORCED CONCRETE FRAME, PATTERNED AFTER THAT CONSTRUCTED FOR THE NEW STATEN ISLAND FERRY TERMINAL IN LOWER MANHATTAN. RESULTS INDICATE THAT MICROCONCRETE MODELS EVEN AT EXTREME SCALE FACTORS, CONFORM TO THE ULTIMATE STRENGTH PROVISIONS OF ACI-318-63 AND ...

Unilateral Damage in Reinforced Concrete Frames

2015
One of the main applications of the lumped damage mechanics or the damage mechanics of dual systems is the earthquake vulnerability assessment of structures. This means not only the consideration of the inertia forces but, mainly, the adequate description of crack propagation under general cyclic loading.
