A New Method of Checking Anti-floating Stability of Buried Horizontal Tank Zubin zhang1,a，Haisheng Bi1,b，Shichang Song2,c 1College of Pipeline and Civil Engineering, China University of Petroleum, Qingdao, Shandong, 266555, China 2Survey, Design＆Research Institute of ZPEB, Puyang, Henan, 457001, China azhangzubin_1@163.com, bbhs888796@163.com, csongshichang2008@126.com Keywords: Anti-floating checking; Buoyant density; Thickness of overburden; Added anchor Abstract.
A new method of checking anti-floating has been brought up to improve anti-floating reliability based on the analysis of existing methods in this paper, meanwhile, several anti-floating measures can be took combined with engineering practice to guarantee the tank body reliable anti-floating performance.
According to the engineering practice, the tank is most likely to be float when the whole overburden layer soaks in water and the tank is nearly no-load.

Prediction on Modal Properties of Building Plates Xianfeng Huang1,2,a , Zhixiang Zhuang1,2,b, Shangyou Wei1,2,c and Junxin Lan1,2,d 1 Guangxi Key Laboratory of Disaster Prevention and Engineering Safety, Guangxi University Nanning, 530004, China 2 College of Civil Engineering and Architecture, Guangxi University, Nanning, 530004, China aseulee@163.com, b164625568@qq.com, c249335371@qq.com, d237404735@qq.com Keywords: Building Materials, Building member, Modal density, Elastic modulus, Critical frequency.
Although there exist only a few researches on modal density in most aspects of engineering including building acoustics, studies focused on the modal density and modal overlap of a plate are seldom to be found.
If statistical averaging is to be meaningful, then there should have minimum modes in a structure, or a building member (a subsystem in SEA).For instance, if a structure has a minimum of 2 modes per band, it is generally to be sufficient though on lightly damped engineering structures more (6 0r 10 per band) may be necessary.
