In the construction energy conservation design May refer to "Civil construction Energy conservation Design standard" stipulated to conserve energy the housing outer wall heat transfer coefficient on limiting value to carry on the design. outer wall keeps warm the system in overseas to be called the EIFS system, namely outer wall heat preservation and decoration system.
"Civil construction Energy conservation Design standard" to the window wall area which faced differently has made the quite strict stipulation, stipulated that “to north, to east and to west, the southing window wall area compared should not surpass 20%, 30% and 35%”.
With the coal-fired boiler heating is causes this area air pollution the primary factor, Our country some north material demonstrated that every 1,000,000 square meter heating area, a heating time need the coal consumption 58,300 tons, arranges the mist and dust 607 tons, discharges CO2 and the nitrogen oxygen compound gas 1208 tons, the ash dregs 8500 tons, causes this area to surpass for 100 days in the heating time air quality exceeding the allowed figure third-level above number of days, causes annual the blue sky engineering effort die young.

It has lots of different kinds of unit types, material depot, analyzing process etc, thus can be widely used in thermal, civil engineerings etc[5].
Engineering example analysis: a five-layer framework office building caught fire, the post-disaster scene investigation collecting photos shown as below: According to the site’s remain appearance characteristics and burning condition:the concrete surface color was shallow gray slightly now light yellow, surface bubbling had more crack and transfixion seam, surface had edge expansion and dilatancy, came off seriously.
In practice,ABAQUS finite element simulation can infer the concrete structural fire temperature and temperature field distribution more accurately, thus provide important technical parameters of mechanical properties and fire component identification and reinforcement for further analysis ,and also can provide engineering and technical references for the spot inspection.

Study on Mechanical Mechanics with Technical Points in Foundation Design of Offshore Wind turbines Bixiang Mei 1, a 1Department of Civil Engineering,Nangchang Institute of Technology, 289 Tianxiang Road, Nanchang 330099, China aemail:809622645@qq.com Key words: offshore wind turbines; mechanical mechanics;foundation; technical points Abstract: By its application environments and structure features,the five key technology issues in foundation design of offshore wind turbines including structure mechanical mechanics analysis, foundation type selection,pile design,wave force calculation,structure fatigue analysis are discussed in this paper.The corresponding technical resolution and research methods are also provided.It is aimed to provide a useful reference for the foundation design of offshore wind turbines. 1 Introduction Wind power is a kind of clean and renewable resources which is helpful for environmental protection ,and has developed rapidly in recent years in the countries
Comprehensive consideration is needed in selecting foundation types including water depth, water level fluctuation amplitude, soil conditions, seabed slope rate and stability, flow velocity and erosion, wind turbines operation requirements, berthing and anticollision requirements, construction installation equipment capability, prefabrication site and transport condition, engineering cost and time requirements of project construction, etc. 2. 3 Questions of pile foundation design According to the characteristics of offshore wind turbines, the vertical bearing capacity is not the dominant factor generally ,and the uplift bearing capacity or horizontal bearing capacity is dominant.
