Introduction At present, the civil aviation flight speed is generally between 500 km to 900 km per hour, the speed of ground traffic incomparable [1].
In recent years, train speed, the car ticket, overnight train bus, train and other measures, although the speed of the train is not up to the flight speed, but the time spent on average only civil aviation ground of 1/3 or less, plus the train punctuality rate higher relative civil aviation, civil aviation fast advantage is often the ground of the time offset many [3].
Civil aviation transportation is safe, comfortable, fast advantages, is an important part of comprehensive transportation system state [4, 5]. 30 years of reform and opening up, with the continuous improvement of economic structural adjustment and economic level, the rapid development of China's civil aviation industry, has gradually become the important strategic support for China's economic and social development [6].

Earthquakes are the most unpredictable damaging loads which can affect civil engineering structures.
Introduction Ground motions are dynamic loads which can affect neighboring, insufficiently separated civil engineering structures by leading them to collisions [1-4].
To simulate the behavior of each structure during seismic excitation, the unidirectional shaking table, located at the Faculty of Civil and Environmental Engineering, Gdansk University of Technology (Poland) was used.

Large-scale public building (LSPB) is different from general industrial and civil construction, so that some special management methods are attained to handling the complex design environment based on sustainable development theory.
Large-scale public building has differences with general industrial and civil construction: l Special importance of product design: once completes in a very long period it would be a landmark in the region.
A statistics result show that the proportion of quality accident of civil engineering caused by design is highly up to 40.1%[2].

Finite element model updating is a well-known technique to better characterize the real behaviour of civil engineering structures.
Introduction Finite element (FE) models are widely used to simulate the behaviour of civil engineering structures.
This fact highlights the importance of the model updating process for the structural assessment of civil engineering structures.
Thus, the model updating method is an available tool to improve the structural assessment of civil engineering structure.

The numerical model was built by the integrated solution system for bridge and civil engineering- MIDAS/Civil.
Fig. 3 shows three dimensional numerical model of the arch-deck bridge built by MIDAS/Civil.
To confirm the calculating precise and fulfill requirement of engineering, the arch is meshed into 58 beam elements in length not longer than 1.0m.
Conclusions The numerical model of reinforced concrete arch-deck bridge was built in details by Midas/Civil.

Besides engineering cost, Li Qingmei [1]holds the perspective of tenders division is also one of the key factors to the quality and duration of the engineering.
What’s worse, the method has a bad influence on the whole engineering.
What’s more , tenders division affects the costs of engineering.

In the last decades, the deployment of aluminium and its alloys in civil engineering fields has been increased significantly, due to the material’s special features accompanied by supportive technological and industrial development.
Conclusions attempt to highlight the advantageous characteristics of aluminium use as well as the potential benefits to the more widespread implementation of topology optimization within the utilization of aluminium in civil/structural engineering.
Successful application of aluminium alloys in structural engineering is connected to its inherent physical and mechanical properties: low density, which allows reduced loads on foundations and easier construction process; excellent corrosion resistance, which reduces its maintenance requirements; and the extrusion process, which allows the production of members with efficient and optimised cross-sections [1].
