Structural Optimization of Elevated Building Yiyang Wang 1, a , Chenchen Wang2,b 1 Hydraulic and Hydro-power Engineering, Hohai University, Nanjing, Jiangsu Province, China 2 College of Architecture and Civil Engineering, Taiyuan University of Technology, Taiyuan, Shanxi Province, China a596540057@qq.com, bwccencn@yahoo.com.cn Keywords: Elevated building, Structural mechanics, Dynamic loads, Connecting bar, Lateral supports Abstract.
The relative references study certain individual structure but hardly mention the engineering-oriented application.
Through the simplification in the aspect of Engineering Mechanics, the typical structure of elevated building can be regarded as two-dimensional member bar system.
Future Work The measures discussed in this paper are not complicated and can be easily taken into utilization in construction and other engineering projects.

It was suggested to regard the safety monitoring of high CFRD as systems engineering, to pay equal attention to safety monitoring of both concrete face slab and to interconfirm their monitoring results.
Thus, it is very important to carry out overall and strong pertinence safety monitoring on deformation, seepage, stress and strain of 200-meter high CFRD, and it is very necessary to pay more emphasis on the relevant research of safety monitoring on 200-meter high CFRD. 2 Safety monitoring principles and requirements for 200-meter high CFRD Foundation Items: National Natural Science Foundation program(50779051); Water Resources and Electricity Engineering Science Open Foundation Key Lab Program of China(2007B037); Special Science Research Planning Program of Ministry of Education in Shanxi(07JK354); Science Research Foundation Program of Xi’an university of technology(106-210509).
Several observation cross sections including the highest section can be selected, and 3 to 6 observation points can be set in each section on different altitudes. 5 Conclusions The safety monitoring of 200-meter high CFRD is a systems engineering and should be all things considered in all monitoring aspects to gain the safety information of dam body and foundation.

It illustrates that numerical simulation can objectively reflect the failure law of rock blasting and provide theoretical and technical guidance for the corresponding practical engineering.
Introduction The explosive stress wave theory has been a major research topic in engineering blasting industry for decades.
In tunnel blasting excavation, additionally, I-grade surrounding rock rarely occurs in practical engineering, and V-grade and VI-grade are not able to get self-stability, so the blasting excavation method is not commonly used in those three rocks. 
Since the material properties of IV-grade rock is soft, it is more easy for blasting to produce a crushed zone in IV-grade rock and the area of crushed zone is larger. it indicates this phenomenon  is accordance with the engineering practice

Although the bar’s height obtained Chapter3 is greater than that of the prototype, it is perhaps useful and helpful for a civil engineer to decide the depth of foot protection.
