【摘要】 生态复合墙结构是一种能就地取材、抗震性能好、施工周期短、节能效果佳、工程成本低等具有多种优势的新型结构体系。作为生态复合墙结构的主要承力构件,生态复合墙体构造独特,当框格形式划分不同时,其破坏形态及受力性能也将发生改变。本文以不同框格形式生态复合墙体为研究对象,通过试验研究与数值分析,探讨不同框格形式对生态复合墙体抗震性能的影响规律,并在此基础上提出基于可拓优度评价法的墙体框格优化评价方法,完成的主要工作有：1.对1／2比例三肋柱生态复合墙体ECW-2进行低周反复荷载试验,介绍墙体的破坏过程及破坏形态；分析了墙体的承载能力、变形、延性、耗能、刚度退化等抗震性能。2.对比分析不同格形式生态复合墙体(三肋柱形式、五肋柱形式、标准墙体)抗震性能；探讨不同格形式对生态复合墙体承载力、延性、耗能、变形能力及破坏模式的影响。3.在前期试验结果及非线性有限元分析的基础上选取评价样本；应用多指标评价方法——可拓优度评价法对生态复合墙体的承载力、延性、耗能能力、变形能力及经济性多种指标综合评价进行择优,较为科学地得出最优框格形式,为生态复合墙体结构实际工程提供了一定的设计依据。更多还原

【Abstract】 The ecological composite-wall structure is new structure system which have many advantages such as using local materials, excellent seismic performance, short construction cycle, good energy-saving effect and low engineering cost etc. The ecological composite-wall, as a major member, is very important to effects of the whole structure system’s seismic performance. The previous study result of the study team can be concluded as follows:These results can be showed that the catch-frame forms have a noticeable impact on seismic performance of the ecological composite walls. Based on the experiment and the finite element numerical simulation analysis in this paper, the seismic behavior and failure mode of the ecological composite wall with three-rib columns have been researched and the regularity which the wall’s seismic performance with different the catch-frame forms have been evaluated. On the basis of this, the best catch-frame form is also put forward based on extension superiority evaluation method. The main research contents are summarized as follows:(1) A group of 1/2 scale model of the ECW-2 ecological composite wall with three-rib columns and straw fiber cement-based blocks is tested under low-frequency cyclic loading in this paper. The composite wall’s bearing capacity, deformation, ductility, energy dissipation, and stiffness degradation are researched.(2) According to the low-frequency cyclic experimental research on the ecological composite walls with different catch-frame forms including three-rib, four-rib, and five-rib columns, this paper contrast analysis wall’s stiffness, bearing capacity, deformability, and energy dissipation capacity’s change law with the catch-frame forms(3) Assessment samples have been selected based on the previous study result and the finite element numerical simulation analysis. applied the extension superiority evaluation method which has bearing capacity, tensile and energy dissipation capacity against the wall and the economic multi-factors so as to choose the most excellent catch-frame forms. It provides designing proofs for practical engineering of the ecological composite wall structure.更多还原
