Structural Dynamic Characteristics Determination Using Response Data in Small Earthquakes Maosheng Gong1,a, Jing Sun2,b, Lili Xie3,c 1Institute of Engineering Mechanics, China Earthquake Administration, Harbin 150080, China 2Institute of Civil Engineering, Heilongjiang University, Harbin 150080, China 3School of Civil Engineering, Harbin Institute of Technology, Harbin 150090, China agmshiem@163.com, biemsunj@163.com, cllxie@iem.net.cn Keywords: Modal frequency, Damping ratio, Earthquake response data, System identification.
The observation systems play an important role in earthquake engineering, because they can monitor and record the seismic response such as acceleration time-histories during earthquakes, and people can check the seismic performance of the building from the acceleration response records.
ARX System Identification Method In earthquake engineering, the system identification is generally used to determine the dynamic properties of structure from its response data.

Design of Approach Slab of Road bridges LACO Kamil1,a and BORZOVIČ Viktor1,b 1 Slovak University of Technology, Faculty of Civil Engineering, Radlinského 11, 810 05 Bratislava, Slovak Republic a kamil.laco@stuba.sk, b viktor.borzovic@stuba.sk Keywords: approach slab, conservative structural model, engineering tool.
Additionally, an engineering tool in a form of useful tables is available for bridge designers.
The aim of this work is to analyse the results and to create a template for a similar engineering tool based on actual design standards (Eurocodes).
It can be assumed that in the future, engineering tools will be able to clearly define a better reinforced edge area.
To complete the engineering tool, optimal design of the transverse reinforcement is necessary with careful approach at the free end of the slab.

Transformers in Architectures-Applicability Study on the Architecture with Mobile Roof Jia-wei Li 1, a,Yu-bo Gao *,2,b 1Taiyuan University of Technology, Shanxi Taiyuan 2Taiyuan University of Technology, Shanxi Taiyuan a470021169@qq.com, bgaoww@126.com (* represents communication author) (College of Architecture and Civil Engineering, Taiyuan University of Technology, 030024) Keywords: mobile roof, open rate, construction cost, multi-function, all weather Abstract: Mobile roof structure is a new type of architecture in which part of, or all of the entire roof can be moved or retracted within a short period of time so that the building with movable roof can be used in open or closed states.
Research status of the mobile roof in home and abroad The studies on mobile roof started from the 1960s, and the Pittsburgh Civil Stadium established in 1961 opened a new chapter for the development of the mobile roof.
Although there have already been engineering projects built, most of them refer to the foreign experience, and there is a lack of conclusion and standard for relevant theoretical knowledge.
As a result, the entire engineering, from design to construction, shall refer to substantial foreign engineering examples.
Faced with the engineering project with so many uncertainties, we shall conduct appropriate evaluation according to our actual condition and select appropriate plans, thus to accumulate engineering experience and to integrate with the international design and construction level in architectures.

Discussion and Suggestion for the Design of Slope Anchor Bolt Kong Xianggang1,2,a, Zhang Xingui1,b, Wang Yang3 1School of Civil and Architectural Engineering, Guangxi University, Nanning, China 2Guangxi Polytechnic of Construction, Nanning, China 3College of Civil Engineering, Tongji University, Shanghai, China aUyx3@163.com, bxgzhangchn@foxmail.com Keywords: anchor bolt, type choose, safety factor, free part length, anchorage length Abstract.
Disperse-type anchor bolt was suitable for soft rock and soil engineering which required higher bearing capacity of the bolt.
The bolt felted endlong was fit for stratum consolidation and some engineering in which small stratum deformation could be allowed.
So, compression-type bolt should be given priority for the permanent anchor engineering.
