Comparative Study on Diagonal Strut Model of infill wall

Structural Durability & Health Monitoring 2018年第3期12卷 169-187页

作者： Zhenling Chai Zixiong Guo Xiaojuan Liu Yunfan Jiang College of Civil Engineering Huaqiao UniversityXiamen361021China

The equivalent diagonal strut models of infill wall mainly include the single strut model and multi-strut ***,several equivalent strut models and their characteristics are introduced in this ***,model analysis and pushover analysis are carried out on infilled frame models with the aid of the software *** typical single strut models and a typical three-strut model are used to simulate the panel of the frames *** is indicated that the period reduction factor of the frame with a three-strut model is close to the value recommended by the current *** infill wall has great influence on the overall stiffness,bearing capacity and weak position of the *** stiffness and the bearing capacity of the infilled frame increase with the increase of the number of the infill *** unfilled story is the weak position of the infilled frame,and when the unfilled story at the bottom of the infilled frame,the seismic response of the upper infill layer decreases with the increasing of the number of unfilled story.

The behaviors of infill wall in earthquakes show that infill masonry walls,which are used as nonstructural elements of concrete frames,are vulnerable when they are subjected to *** order to achieve an optimal antiseismic behavior,or even stability,two methods of connection are *** shaking table tests,with 1:3 scale walls of two-storey model subjected to horizontal earthquake loads,were carried out to investigate the out-of-plane behaviors with different connections between walls and *** test results show that the connection methods employed between walls and beams have a significant effect on the out-of-plane stability of infill *** walls bound by bars with the beams perform better than those with inclined bricks without gaps.

The interactions between reinforced concrete(RC)frames and infill walls play an important role in the seismic response of frames,particularly for low-rise *** walls can increase the overall lateral strength and stiffness of the frame owing to their high strength and ***,local wall-frame interactions can also lead to increased shear demand in the columns owing to the compressive diagonal strut force from the infill wall,which can result in failure or in serious situations,*** this study,the effectiveness of a design strategy to consider the complex infill wall interaction was *** approach was used to design example RC frames with infill walls in locations with different seismicity levels in *** performance of these frames was assessed using nonlinear static,and dynamic *** performance of the frames and the failure modes were compared with those of frames designed without considering the infill wall or the local *** was found that even though the overall responses of the buildings designed with and without consideration of the local interaction of the infill walls were similar in terms the overall lateral strength,the failure modes were *** proposed method can eliminate the column shear failure from the ***,the merits and limitations of this approach are discussed and summarized.
