Study on the Measure of Reducing Noise and Vibration of Over-track Buildings Induced by Crane Load Huajie ZHOU (School of Civil Engineering and Architecture, Wuhan University of Technology, Wuhan 430070, China) zhouhuajiemetro@126.com Keywords: Subway; over-track building; vibration; noise; measures of reducing noise and vibration; crane load Abstract: Big vibration will be cause by train load and crane load in the over-track buildings, and then generate structure-borne moise in the buildings, which will affect the live quality of the people lived in the buildings greatly.
Focusing on this proble, three finite element method is established based on a practical engineering.
The research results in the paper have strong engineering practicability and can provide some references for some other projections in China in future.
Fig.1 Space distribution of crane load and vibration transmission 1 Engineering Situation There are 8 three-layer appartment on the platform, which is just above the storehouse and there will have subway trains and crane running across it (Figure 2).
Engineering prediction of railway vibration transmitted in buildings.

Introduction With the rapid development of civil aviation, aircraft load increased rapidly, airport pavement as one of the most basic and most important establishment of a civilian airport, for flight safety, air traffic and airport operational efficiency have a major impact; airport pavement of large transport aircraft of the future must also have good adaptability.
So in this article, plain concrete and polyacrylonitrile fiber concrete fatigue performance, impact resistance and flexural toughness will be analyzed and compared, and studied polyacrylonitrile fiber classification value of airport pavement classification number (PCN) to improve results for practical application of engineering in providing theoretical support.
Airport pavement will be blew by the wake of the jet engine, according to observations on site, generally the temperature of civil transport aircraft engine wake spreading to road surface does not exceed to 150˚C.

In order to meet the installation of equipments, civil work is relatively large.
It needs relatively little amount of civil engineering work and low costs.
Battery swap station, as civil fundamental Infrastructure servicing for electric cars, Should meet the general requirements.Therefore, to research and constitute the criterions is particularly urgent in the current.

Design of concrete slabs reinforcement – methods of FEM results interpretation incorporating twisting moments BARTÓK Andrej1, a * 1Slovak University of Technology, Faculty of Civil Engineering, Radlinského 11, 810 05 Bratislava, Slovak Republic aandrej.bartok@stuba.sk Keywords: concrete, slab, twisting moments, slab reinforcement design Abstract.
But structural engineers work with structural analysis software, based mainly of finite element method (FEM).
It is common, that design engineer doesn’t know, which method his program uses.
Structural engineer should know, what method his software use.
Experienced engineer can write own algorithm.
