Moment redistribution in continuous prestressed concrete beams
Magazine of Concrete Research, 1972Synopsis In a previous paper relationships between moment and average curvature were developed for prestressed sections subjected to constant moment. The variation of stiffness due to concrete tension between cracks was taken into account. These relationships are now used to determine the moment-load and load-deflection curves for continuous beams up

Serviceability influences on moment redistribution in beams
Structural Concrete, 2005Moment 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 continuous profiled steel?concrete composite slabs
Magazine of Concrete Research, 2001The moment redistribution behaviour of continuous cold-formed profiled steel deck and concrete composite slab was studied both experimentally and numerically. An experimental programme consisting of three two-span continuous composite slabs was performed.

Study of Moment Redistribution in Prestressed Concrete Beams
Journal of Structural Engineering, 1997This 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 ...

Redistribution of Moments in Spandrel Beams
ACI Structural Journal, 1991In 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.

Redistribution of moments in prestressed concrete continuous beams
Magazine of Concrete Research, 1966Summary Twenty-seven three-span and twelve two-span beams, all of rectangular cross-section, were tested to destruction under various arrangements of concentrated loads. The results of these tests are presented. Redistribution of moments was practically complete in the majority of the beams.

Review of moment redistribution in statically indeterminate RC members
Engineering Structures, 2019Abstract Moment redistribution is a specific behaviour in statically indeterminate reinforced concrete (RC) structures due to the structural redundancy and nonlinear characteristics of the reinforced concrete. Considering moment redistribution in practical design is an effective way to fully exploit the reserve capacity of the materials and to ...

Moment Redistribution in RC Beams Retrofitted by Longitudinal Plating
Advances in Structural Engineering, 2006The ability to redistribute moment within a reinforced concrete frame or structure is an intrinsic requirement in design. This is generally dealt with using the established neutral axis depth factor, the ku approach, with fixed hinge lengths, which require the flexural member to fail by concrete crushing and which, in turn, requires large strains in ...

Redistribution of Moments - from Serviceability to Ultimate Limit State
Structural Engineering International, 1998This paper examines the redistribution of moments in linear reinforced concrete elements. The usual assumptions are that: (1) internal forces are calculated based on small-deflection theory; (2) deflections are small and deformations are finite throughout the whole loading history; (3) strain distribution in sections is linear; (4) shear deformations ...
