Application Of New Crop Straw Composite Wall

In order to implement sustainable development strategies, to realize the national energy conservation, it is very imminent to carrying out green building materials. Straw wall materials use the straw resources effectively, reduce the pollution of buring and building energy consumption significantlystraw, improve the indoor thermal environment effectively. The research of Straw wall materials has great practical significance to ease the energy shortage situation, promote low carbon economy and sustainable development.This paper made a systematic study of straw wall mechanical properties, thermal properties and fire performance. Combined with Yangling Demonstration model room, the application form and the structure measure of the straw wall has carried on the thorough careful investigation. This paper takes method which combines the method of actual measurement with theoretical analysis, has obtained a preliminary straw composite wall material thermal performance parameter index and proposed the structure measure and the connection method. It shows that the light steel– straw wall structure heat transfer efficiency is low, better to resist the outdoor thermal environment. Periodic steady-state thermal analysis has completed with finite element analysis software—ANSYS to Confirmation the reliability of the straw wall thermal properties. For different types of sheet, different insulation materials and different keel wall thickness of the composite were compared with simulation analysis, to propose the improved techniques method of the crop straw wall.In order to further grasp the straw wall adaptation in the earthquake region, and according to the light steel - straw wall structure be attributed to the typical characteristics of skin effect of a conventional structure, the performance of its force structure has been optimized formula and theoretical verification. Combined with the straw wall project of the post-disaster reconstruction in Sichuan Mianzhu region, the mechanical properties of the straw wall structure is analysied by ANSYS finite element, obtained stress-strain diagram, contrasted the values of the simulation results and theoretic calculation, shows that light steel – straw wall Lateral performance fully meet seismic design requirements specification and has a good seismic performance.In summary, the straw composite wall material is a lightweight, high strength, and sustainable use of the green wall materials, straw composite wall construction has excellent thermal properties and seismic performance, It is suitable for promoting the use of large areas of China, has a certain value engineering, and the results of the straw composite wall material provide new ideas of promoting the building of green homes and sustainable development.
