This paper investigates flexural behavior of P.S.T (Prestress Segment Tunnel) method rahman structure according to joint welding through an experimental study. For the experimental study, three specimens, non joint welding specimen and two joint welding specimens, were fabricated. As a result, the joint welding specimen, especially the bottom steel joint welding specimen is the most superior in flexural strength.

The purpose of this experimental study is to develop the waterborne silicon acrylic finishing material of parking lots. Resistance-Wheel moving load test was conducted in order to supply basic datum for developing the material by implementing modified polyamide resin. As a result, all the specimens were satisfied by the quality standard regarding dynamic wheel load resistance which is prescribed in KS F 4937. As conclusion, this study confirmed that developed finishing material could be an optimum surface finishing material capable of applying for parking lots’ floors.

The purpose of this experimental study is to develop the waterborne silicon acrylic surface finishing material of parking lots. Adhesion strength experiment was conducted in order to enhance performance of the finishing material by adopting modified polyamide resin. The results qualified the standard regarding bond strength which is prescribed in KS F 4937. They are confirmed that the strength tend to increase as the amount of polyamide increased and could be an optimum surface finishing material applicable for parking lot floor.

이 연구에서는 유전자 프로그래밍을 활용하여 슬래브-기둥 접합부의 유효압축강도를 산정할 수 있는 통합모델을 제안하였다. 81개의 외부기둥 데이터와 44개의 내부기둥 데이터를 바탕으로 유전자 프로그래밍이 수행되었으며, 통합모델은 기존모델 대비 우수한 유효압축강도 예측정확도를 가지는 것으로 나타났다. In this study, an unified model that can estimate the effective compressive strength of the slab-column joint was proposed using genetic programming (GP). GP analysis was performed based on 81 external column data and 44 internal column data, and the unified model showed superior estimation accuracy on the effective compressive strength compared to the existing models.
