Serviceability influences on moment redistribution in beams

Structural Concrete, 2005
Moment redistribution has traditionally been considered as an ultimate limit state (ULS) phenomenon closely linked to considerations of reinforcement ductility. This paper demonstrates that a significant proportion of this redistribution will frequently occur at the serviceability limit state (SLS) because of the mismatch between the flexural stiffness

Moment Redistribution in Precast Concrete Frame

Journal of the Structural Division, 1970
Three full-size precast concrete gabled frames were tested to destruction. These frames were instrumented and tested to determine the amount of moment redistribution that occurred at high overload. Each frame was 40-ft wide and 18-ft high. High strength reinforcement was used.

Moment redistribution in structural concrete codes

Canadian Journal of Civil Engineering, 1991
Features of current moment redistribution provisions in American and European structural concrete standards are reviewed and compared. Some major differences are identified, along with their common objective of ensuring the rotation compatibility at the ultimate limit state of continuous structures.

Moment Redistribution Caused by Beam Fracture in Steel Moment Frames

Journal of Structural Engineering, 2000
This paper presents an analytical study on static moment redistribution and resultant reduction of lateral resistance caused by sudden beam fractures in steel moment frames. A numerical example is presented for a simple multispan frame, and the step-by-step processes of beam fractures, moment redistribution, and loss in resistance under statically ...

Redistribution of Moments in Spandrel Beams

ACI Structural Journal, 1991
In 1977, the ACI Building Code introduced a torsional limit design method for the design of spandrel beams subjected to torsion. This very economical method utilized the redistribution of moments between the spandrel beam and the adjoining floor beams.

Moment Redistribution in Reinforced Concrete Structures

1991
In the design of concrete structures, the criteria of strength and serviceability must be met. It is of equal importance that a structure be economical to construct and maintain. Current design codes require strength design, supplemented by checks for serviceability.

SECONDARY MOMENT AND MOMENT REDISTRIBUTION IN CONTINUOUS PRESTRESSED CONCRETE BEAMS

PCI Journal, 1972
THE 1971 ACI BUILDING CODE PROVISIONS ARE EXPLAINED FOR MOMENT REDISTRIBUTION IN CONTINUOUS PRESTRESSED CONCRETE BEAMS. BY MEANS OF EXAMPLES, EMPHASIS IS STRESSED FOR WHEN THE SECONDARY MOMENTS DUE TO PRESTRESS FORCE ARE TO BE INCLUDED IN DETERMINING THE ULTIMATE CAPACITY OF CONTINUOUS BEAMS. /AUTHOR/

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.

Inelastic Moment Redistribution for Bridges

Journal of Structural Engineering, 1995
A simplified procedure is presented for redistributing moments caused by inelastic hinge rotations that accompany shakedown of continuous bridge girders under repeated live loadings. This inelastic moment redistribution procedure (IMR) is very similar to that of elastic moment distribution except that inelastic hinges, not girder joints, are initially ...

Study of Moment Redistribution in Prestressed Concrete Beams

Journal of Structural Engineering, 1997
This paper describes an investigation into the redistribution of moments in certain composite concrete beams. Seven two-span beams 6.2 m long were constructed and tested by means of applying two point loads at midspans. Each beam comprised two precast beams made continuous by a top flange cast “in situ.” Since the term “redistribution of moments” is ...
