It has two walls, between which there is insulating material.
Material storage load is the main consideration of load in the analysis.
If the height of silo is large, the values of material storage load at the top and the bottom differ greatly.
Therefore, material storage load is the main research object.

It is preferable to develop eco-friendly green composite instead of using oil based material.
Higher process temperature decreases the strength of single jute fiber, however it facilitate fiber dispersion inside the material 4.

Experimental Materials.
From the graph, the higher temperature for the heat treatment the greater the stress when plastic deformation first happened; between 300 ˚C to 500 ˚C, higher temperature makes hyper elastic hysteresis curve more fruity, material of SME improved; When temperature exceed 600 ˚C, with the rise of temperature the inverse phase become less obvious and residual strain is larger when unloading.
Conclusion With lower temperature in heat treatment, it not entirely translate from austenite Ni-Ti to martensite in the structure of Ni-Ti alloy ultra thin wires, it’s austenite Ni-Ti primarily in internal crystalline phase, As the temperature rise in heat treatment, austenite Ni-Ti volume becomes bigger, the larger the alloy hysteretic parcel area, the better the shape memory effect for Ni-Ti alloy ultra thin wires; When the temperature is exorbitant, Ni-Ti internally generated excessive austenite Ni-Ti grain, that make its internal defected, thus Ni-Ti alloy stress-strain curve get closer to the general elastic-plastic materials during the uninstall part, the alloy severely damaged in this situation, then SME is not obvious.

At present, in the construction field ,whether in the lower-rise, middle-rise, even high-rise building, organic heat preservation material is mainstream materials for the current exterior wall thermal insulation system in our country. the biggest advantage of organic heat preservation material is qualitative light, good heat preservation, and the biggest disadvantage is poor fire safety and easy ageing.
When combustion smoke and is toxic, organic heat preservation material bearing quality and use fixed number of year are lower than the inorganic insulation materials.
Through various organic materials exterior insulation system fireproof performance test, fire safety of materials and structure elements are researched for external thermal insulation system[3], fire safety higher exterior insulation system is found to reduce the hidden danger of fire, and reduce fire facilitator action of exterior insulation system when the fire broke out[4] [5] For building exterior insulation system whether to adopt cavity structure(part sticky glue or full), organic insulation layer whether to adopt fire points warehouse or whether fire belt, organic heat preservation material surface whether to adopt thick fire protection layer, external wall thermal insulation system fireproof performance is researched by the fire performance experimental comparison.
To sum up, exterior insulation system composed of organic material insulation system(for example PPB and PPS system) can satisfy the requirement of fire through some structural measures.
