【摘要】：我国经济和社会的快速发展让高层建筑迎来了巨大的发展机遇。然而由于施工管理上存在漏洞等诸多原因,经常造成结构质量存在各种各样的工程问题,其中混凝土质量不满足设计要求是较为常见的一类工程问题,因此对此类问题的系统研究具有重要意义。本文研究的高层混凝土结构施工中剪力墙置换方法可以很好的解决剪力墙混凝土质量问题,首先通过两种以上的有限元软件对不同工况下结构和构件的受力状态进行对比分析,并相互校核结果的准确性,为后期的设计提供理论依据。其次依据验算结果确定施工阶段的分层分段设计,并采用软件对每区段的卸载装置进行研究分析,设计出由钢结构卸载装置与钢管支撑架支撑相结合的支撑方案。最后在施工过程中对结构构件进行应变监控与位移监测,确保施工过程中结构的安全以及置换加固的顺利进展。本文结合工程实例,将研究的方法运用于其中。通过MIDAS与PKPM软件对结构进行了分析研究,设计并验算了相应的支撑卸载装置,并通过施工过程中的监控确保了施工过程的顺利完成,取得了良好的工程效果。本文对类似的工程提供了理论及参考价值,具有良好的工程实际意义。
[Abstract]:The rapid development of economy and society of our country makes the high-rise building welcome enormous development opportunity. However, due to many reasons such as loopholes in construction management, there are often a variety of engineering problems in structural quality. The concrete quality does not meet the design requirements is a more common kind of engineering problems. Therefore, the systematic study of this kind of problems is of great significance. The shear wall replacement method studied in this paper can solve the problem of shear wall concrete quality very well. At first, two kinds of finite element software are used to compare and analyze the stress state of structures and members under different working conditions, and verify the accuracy of the results. For the later design to provide theoretical basis. Secondly, based on the results of checking calculation to determine the construction stage of the layered design, and software to each section of the unloading device for research and analysis. The support scheme is designed which is combined with steel structure unloading device and steel pipe support. Finally, strain monitoring and displacement monitoring are carried out in the construction process. In order to ensure the safety of the structure and the smooth progress of the replacement reinforcement during the construction process, this paper applies the research method to the project example, and analyzes and studies the structure by MIDAS and PKPM software. Design and check the corresponding supporting and unloading device, and through the monitoring of the construction process to ensure the smooth completion of the construction process, achieved good engineering results. This paper provides a theoretical and reference value for similar projects. It has good practical significance in engineering.
