Recently the construction of railway sections passing the central area of cities and stations under railway lines are increasing, and then it is urgently required to take the countermeasures against the railway vibration and the second-phase noise radiated from it. The most efficient countermeasure, out of technologies developed up to now, is the floating slab track which is the track system isolated from the sub-structure by springs. In other countries, the source technologies for anti-vibration design and vibration isolator - one of key components - have been developed and many installation experiences have been accumulated. However, in Korea, since the system design technology and technologies for key components are not yet developed, the foreign system are being introduced without any adjustment, and the key component, vibration isolator, depends on imports. Thus, the rate of technology self-support is very low. Therefore, to achieve the competitiveness in domestic and overseas markets, the core technologies of floating slab track and its components should be developed immediately.

Recently, railway has been pointed to the efficiency of transportation, rapid transit, and comfortable train ride. the construction of railway near the downtown area and station building are increasing for maximization of utilization and convenience. but the heavy of transportation and rapid transit lead to increase noise and vibration. the noise and vibration of railway may cause the civil appeal, decline in the serviceability and insufficiency of environmental standard. Therefore, the solution to avoid environmental matters becomes one of the most important factor in constructing railway. In this study, analysis fatigue stress joint of low vibration floating slab-anti vibration equipment is carried.

Recent emphasis on southwest coast of bridge construction plans were announced, including cable stayed and suspension bridge design and construction of long span bridge. 1st core tasks of Super Long Span Bridge R&D Center core technology for long span cable bridge(main span 2km+ suspension bridge, 1km+ cable-stayed bridge) with business objectives, self-anger and budget savings in the domestic business, with Bridges overseas business that aims to advance. However, the long-span bridge engineering design of the national independence of the technology as a critical underlying technology abroad, compared with domestic design skills 2-4 years of the technology lags far enough, and reliability-based design for extreme events such as the part of In the field entirely dependent on foreign technology and there. The dependence of foreign technology and international competitiveness in order to escape this study, the main unit of the absence of long span cable bridge to establish the elements of the performance evaluation of the major units of the bridge was suggested that the absence of performance evaluation factors.
