Several Problems Existing in Modern Decoration Design Viewed from Engineering Management Weidong Zhu1, a, Yingying Zhang2,b and Yixin Chen3,c 1China Institute of Water Resources and Hydropower Research, Beijing,100048,China 2Zhejiang University of Water Conservancy and Hydropower, Hangzhou,Zhejiang,310018,China 3The Civil Engineering Department,China Agricultural University,Beijing,100083,China azwd_21@163.com, bhzzyyzy@163.com, cchenyx@163.com Keywords: Decoration design, Design culture, Theme, Material selection, Change of design, Assessment.
From viewpoint of engineering manager, four typical problems existing in current decoration design are analyzed and their causes are pointed out.
The theme of decoration engineering has its own characteristics different from other engineering in several factors in the idea, positioning, functions and social influence of the project, and the said theme shall penetrate in the entire construction process.
The decoration designer shall be the excellent talent integrating with excellent artistic and engineering quality and development capacity.
In the age of fast economic development, the issues of social benefits shall be always noted by each engineering technical personnel.

This study will do residence design collision detection; engineering building quantitative statistics; construction management and property maintenance in the whole building life cycle based on BIM technology.
All of these positive attempt increased the engineering structural components prefabricated level and progress in the projects, and lay the theory foundation for this study[3].
Construction guidance At the construction site, the 3D building information model will be displayed in front of engineers with the paper drawing on Ipad mobile terminal Autodesk BIM360 Glue synchronous database. 
The engineers could instantly do the installation guide for the construction node structure and complex electromechanical equipment.
The Conclusion This study is a positive attempt on the application of new technology in the field of civil buildings.

The Experimental of Shearing Mechanical Properties on the Connectors of Sandwich Insulation Wallboard Xianhong Menga,Zhen Sunb School of Civil Engineering, Shenyang Jianzhu University ,Shenyang ,Liaoning asjzuxianhong_meng@foxmail,b2536726148@qq.com Keywords: Shear capacity;GFRP bars;Cracking displacement;Cracking load Abstract: This paper is aimed to research on bending of shearing strength about the three different kinds of GFRP connectors, determining shearing mechanical properties of GFRP connectors, and providing the reference so as to apply in engineering practice as soon as possible.
Based on this, through the GFRP bars reinforced anchor shear test ,study the mechanical properties of GFRP bars reinforced shear connectors ,and its insulation in sandwich wall panels providing the basis for practical engineering applications .
