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 ...

Moment Redistribution in Reinforced Concrete Structures
1991In 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.

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.

Partial Moment Redistribution in Cold‐Formed Steel
Journal of Structural Engineering, 1985On the basis of the failure criteria developed in an earlier paper by the writers, the utilization of partial section plastification in cold‐formed steel flexural members is presented. As in the limit design procedures developed for reinforced concrete, failure is defined in terms of the strain capacity of stiffened compression flanges, for specified ...

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.

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

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.

Redistribution of joint moments during walking in patients with drop-foot
Clinical Biomechanics, 2010The purpose of the study was to analyze the distribution of net joint moments in the lower extremities in patients walking with a drop-foot compared to a group of healthy subjects. A drop-foot causes the patient to walk with a characteristic limp and it was hypothesized that the drop-foot could lead to increased loadings of one or more joints.Six ...

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 ...
