However, there are some shortcomings to be further improved in the safety criterion: its calculation process is comparatively complex and values of certain parameters can try to be listed for the users to directly query; the safety criterion must be demonstrated by repeated practical engineering cases before its wide applications.

The Comprehensive Study about Fireproof and Single Insulation Walls for Cold Regions Wanzhi Cao1, a, Hongzhen Wang 1,b and Qingxia Sun2,c 1School of Civil Engineering, Northwest University for Nationalities, Key Laboratory of New Building Materials and Building Energy Conservation in Gansu Province, Lanzhou China 2Shandong Urban Construction Vocational College, Jinan China acaowanzhi2029@126.com, blzhfkjwhz@126.com, csunqingxia1982@163.com Keywords: Porous Lightweight Concrete; Wall Products ; Building Energy Efficiency; Durable Fire Prevention Abstract.
This paper introduces the material composition, structure characteristics, product performance, technical and the engineering application supporting technology on non-bearing wall material of thermal insulation and durable fire integration —break hot energy-saving composite block.
It provides important buildings and high-rise building with the age of 100 years and the general construction with the age of 50-100 years in “General civil design”.
The project in the Northwest and Shan dong has promoted and used for 5 years, 8 achievements, more than 300 engineering applications, a total of 550,000 cubic meters or more, sales is more than 210 million Yuan, profit is more than 55.74 million Yuan, the amount of 590 million Yuan has been saved.

In summary, the following conclusions as well as some general remarks for engineering practice can be formulated: - the analysis of the dynamic response of the shell with the assumption of uniform seismic excitation indicated that the concrete material of the shell remained elastic with no tensile damage, - the tensile damage (cracking) in some thin parts of the tower appeared and the elastic stiffness of the concrete was degraded when the model of asynchronous kinematic excitation was considered.

Study on Modification of Rammed Earth Material in Mountain Areas Yun WANG Department of civil Engineering & Architecture, Shaanxi University of Technology, Hanzhong 723001,China awangyun411@126.com Key words: raw-soil; modification; compaction test; direct shear test Abstract: In order to explore the proper modified materials of the raw-soil building in mountain area, the raw-soil modified materials now being used commonly are analyzed effectively at first, and the natural reborn starch resource is thought which has a promising application prospect.
Soil modified by cement appeared a long time ago, and it got extensive use in engineering, but it can bring a great disadvantageous influence on the ecology of raw-soil building.
