CONSTITUTION: A method for connecting the upper plate (300) and both walls (200) of rahmen structure includes: a step of installing the walls at a bottom plate; a step of connecting inner reinforcing bars (210) overlapped in corner part spaces using corner part longitudinal reinforcing bars (600); and a step of burying the corner part longitudinal reinforcing bars in the inner reinforcing bars with placing concrete in the corner part spaces. A vertical wall-shaped outer finishing plate (220) is upwardly extended from outside the upper side or side of the wall. The corner part spaces are formed by mounting the upper plate between upper sides inside the walls. The inner reinforcing bars are extracted from the upper sides of the walls and the end portions of the upper plate. The inner reinforcing bar is formed into a U-shaped ring.

Abstract: PURPOSE: A clinometer using a fiber bragg grating sensor is provided to enable gradient to be accurately measured at high precision since deformation rate according to gradient is measured using the fiber bragg grating sensor. CONSTITUTION: A clinometer using a fiber bragg grating sensor comprises optical fiber(10), circular frames(20), and a rotating pendulum(30). The optical fiber comprises a fiber bragg grating sensor for measuring deformation rate. The circular frames are arranged at a given interval. The optical fiber is wound on the circular frames in a tension state, and thus the circular frames maintain a free-strain state in the tension direction of the optical fiber. The rotating pendulum comprises a rotor(32). The rotating pendulum is able to rotate toward a vertical direction, in which gravity always is applied. One end of the rotating pendulum is coupled to two optical fibers, which are wound on the circular frames and are arranged side by side.

Abstract: A cable bridge is provided to reduce the weight by using a crank-type concrete edge girder instead of conventional rectangular edge girder which is thick and requires a separate element for supporting the bridge deck. A cable bridge(1) comprises a bridge deck(2) in which crank type concrete edge girders(3) are installed to support the deck put on the lower flange of the concrete edge girder and a cable(4) is coupled to the upper flange of the concrete edge girder to support the concrete edge girder. The concrete edge girder is composed of the lower flange(31) supporting the outer side of the deck, a vertical part, and the upper flange(32) which is protruded in the opposite direction to the lower flange in which the cable is penetrated and fixed.
