This study introduces the structural analysis and the testing results of the composite structure which is applied to tilting train in Korea. The composite structure is made of aluminum honeycomb structure materials like a sandwich. The static load test was performed to evaluate the structural characteristic and stability of the composite structure. Considering the vertical, compressive, torsional load and 3-point supporting type as a testing terms, the structural stability of a carbody was evaluated. Load test are based on "Performance Test Standard for Electrical Multiple Unit" with the reference code JIS E 7105. The test results have been very safety and stable for design load conditions.

This study is an experimental research on using stainless steel car body structure for urban railway vehicles. The car body used in the experiment was made of stainless steel. To evaluate the structural characteristics and safety of the stainless car body, static load test was carried out by means of "Performance Test Standard for Electrical Multiple Unit" with the reference code JIS E 7105. The structural safety of the car body was evaluated by implementing vertical load, horizontal compressive load, twist load, and 3-point support tests. Test results verified that the structural safety of a car body was very stable and safe under design load conditions.

This paper describes a carbody structural analysis and the result of its loading test. The purpose of this study is to evaluate the safety and functionality of the body structure operating under maximum load. Aluminum alloy was used as the body structure’s material. The body structure consisted of side frame, under frame, roof frame, and end frame. Of these components, the side frame and under frame were the most important components considering the vehicle and passenger loads. Both structural analysis and loading test were performed under the condition based on "Performance Test Standard for Electrical Multiple Unit" with the reference code JIS E 7105. The test results showed that the body structure is safe and stable under the condition of designed load.

Fabricated hollow slab bridge is commonly used in China. It is indicated that the hinged joints between hollow slabs are easily damaged. Especially under the erosion of chloride salt, the destruction process of hinged joints will be greatly exacerbated. In this paper, deicing salt environment was simulated in the lab to corrode the commonly used hinged joints. According to static load test results, hollow slab coordinated working coefficient is explored and the regression calculation formula was established. Then, the time-varying function of the rate of hinged joint steel corrosion was introduced to the regression model. Finally, the constantly evaluating of the hinged joint durability performance of common used deep, middle and low hinged joint forms were also carried out.
