Loess Foundation—Multi-ribbed Composite Wall Structure Interaction Shaking Table Test Research

Multi-ribbed composite wall structure is a kind of low carbon, environmental protection, green energy-saving building insulation, and with earthquake shock absorption performance is good, fast construction speed, high social benefit and economic benefit etc. The system into the comprehensive promotion stage at present,because the multi-ribbed composite wall structure is still in use rigid foundation assumption of calculation and analysis design method, and the optimization of the design method and innovation research has to be continued. Paper based on the development of the early discovers, relies on the national natural science fund project funding, adopt the method of model test for the loess region of multi-ribbed composite wall structure under the condition of considering the interaction between soil and structure, the shaking table test research, the main work is as follows:(1) According to the characteristics of the multi-ribbed composite wall structure model test and research significance, and put forward the theoretical basis and design method of model test, summarized the model test data processing steps and the shaking table model test data analysis method, provide a theoretical design principle to the model of multi-ribbed composite wall structure design,and How to deal with the shaking table test data after appropriate processing steps and analysis method.(2)Based on the research of the theoretical basis and design method of model test,and combine with the unique structure form of multi-ribbed composite wall structure, the reference has built a prototype structure according to the test purpose and requirements,to design a reasonable scale of the model, completed the design and manufacture of the multi-ribbed composite wall structure model specimen and finished the scheme design oftwo large shaking table test.(3) By considering and not considering SSI effect(Soil- Structure Interaction,abbreviation SSI) of multi-ribbed composite wall Structure shaking table model test data analysis, and carried on the analysis and comparison analysis respectively to the experiment phenomenon, the dynamic characteristics and dynamic response and so on,summarized under the earthquake the action of SSI effect on loess region affect the characteristics of multi-ribbed composite wall Structure system, provide the reference basis for the future of design optimization and improvement for multi-ribbed composite wall Structure.
