Reinforced Concrete Subjected to Restraint Forces

2011-10-24  In this master’s project, the behaviour of reinforced concrete subjected to restraint forces has been studied. In Sweden the design methods normally used are unsatisfactory in order to predict the cracking process of structures subjected to restraint forces. When predicting the number of cracks that will appear and also the

Thermal-induced restraint forces in reinforced concrete

2014-10-1  At a fire temperature T, due to the strength deteriorations of both concrete and reinforcing steel, the column M–N interaction diagram regresses to a smaller shape, so-called T-diagram (Fig. 1(b)). If there is no axial restraint, point I would move horizontally to point I 1 at the constant axial force N 0 and a bending moment M I1 greater than M 0.This movement is due

Crack Control of Concrete Structures Subjected to

2011-9-23  When concrete is subjected to shrinkage, a need for deformation will occur. If this deformation is restrained, restraint forces will appear. When a concrete member is cast against an existing concrete member restraint forces may occur due to different needs of movement, which may lead to cracking. Two specific cases are when edge
