Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 3,   Pages 259-266 doi: 10.1007/s11709-011-0114-x

Abstract: A retrofit of an existing 11-story steel reinforced concrete frame that features the innovative use of post-tensioned rocking walls and shear steel dampers is presented. The main components of the retrofitting plan and important design considerations are described. The retrofitting system is expected to effectively control the deformation pattern of the existing structure and significantly reduce damage to the existing structure during major earthquakes.

Discrete element method modeling of corn-shaped particle flow in rectangular hopper

He TAO, Baosheng JIN, Wenqi ZHONG, Xiaofang WANG,

Frontiers of Structural and Civil Engineering 2010, Volume 4, Issue 2,   Pages 267-275 doi: 10.1007/s11709-010-0035-0

Abstract: Discrete element method (DEM) was developed to simulate the corn-shaped particles flow in the hopper. The corn-shaped particle was described by four overlapping spheres. Contact force and gravity force were considered when establishing the model. In addition, flowing characteristic of particles in the hopper was studied. The effect of friction coefficient on the wall pressure, voidage and velocity distribution was analyzed. The results show that the discharge rate decreases with the friction coefficient increasing; and the “over-pressure” phenomenon occurs in the discharging process for two different friction coefficients. The voidage also increases as the friction coefficient increasing. And the velocity distribution is more uniformity and is closer to the mass flow with the friction coefficient deceasing.

Theoretical Analysis of Creep and Shrinkage Effects in SRC Arch Bridge

Xie Xiaoli,Qin Rong,Peng Wenli,Deng Zhiheng

Strategic Study of CAE 2001, Volume 3, Issue 3,   Pages 80-84

Abstract:

In this paper, the concrete creep theory, compatibility equations, median theory and equilibrium conditions are used and the elastic aftereffect of concrete and creep shrinkage features of concrete restrained all around are considered to develop formulae of cross-section stress redistribution resulted from concrete creep and shrinkage. The formulae which are simple and convenient to use are applied to Wanxian Changjiang Bridge (420m in span) for the model test analysis of creep and shrinkage. The obtained results are compared with those of model test and the agreement between them is very good. The main factors to affect the stress of this type of bridge are indicated.
