The Damage Process And Rebars Arrangement For The Reaction Wall

The reaction wall is the large special structure,which has the characteristics of high bearing capacity and rigidity etc..Nowadays,As the number of domestic and international reaction wall is increasing,there is no specification for it and the research is relatively rare.So it is necessary to research the feature of reaction wall’s damage and the design method for the reaction wall.In this study,ABAQUES is used to simulate the stress change and damage process of the reaction wall under different working conditions.Because the beam is the weakness part in whole structure,the paper discuss the reinforcement scheme of coupling beam.At last,the reinforcement methods of the stiffening wall is discussed by using the model of the reaction wall.The conclusion of the study are as follows:the coupling beam is the weakness part which is under the most complex loads,and also it damages earliest.Compared with the ordinary reinforcement scheme,diagonally reinforcement scheme and Lozenged reinforcement,the diagonally reinforcement scheme makes a better anti-damage ability and high economic benefit for coupling beams.The reaction wall stiffening wall doesn’t need to be arranged by the traditional reinforcement which is commonly used in shear wall,but arranged by a simplified reinforcement.When the reaction wall’s stiffening wall arrange prestressed reinforcement,crack development of beams is restrained.
