강도비에 따른 FBP를 적용한 철골 커플링보 접합부의 변형특성
송한범,이원호 대한건축학회 2007 大韓建築學會論文集 : 構造系 Vol.23 No.5
The usefulness of walls in the structural planning of multistory buildings has long been recognized, When walls are situated in advantageous position in a buildings, they can be very efficient in resisting lateral load. Specially, coupled shear wall system is the primary lateral load resisting system of buildings. It is customary to refer to such walls as being "coupled" by coupling beams. The coupling beams must exhibit excellent strength, stiffness, ductility and energy dissipation capacity. To achieve these demands, steel coupling beam with Face Bearing Plate (FBP) embedded in the reinforced concrete walls is proposed. A comprehensive experimental test involving 2 steel coupling beams with FBP embedment length 240mm and 300 mm has been performed. Through experimental study, the evaluation of the seismic performance and deformation characteristic of steel coupling beam joint with FBP was establish.

Reinforced concrete coupled shear walls in tall buildings are known as efficient structural systems to provide lateral resistance to wind and earthquake. The coupling beams connecting two shear walls are normally subjected to very high shear stresses and must before the wall piers, behave in a ductile manner, and exhibit significant energy dissipation characteristic. This paper reports experimental study to investigate the behavior and shear force of the SRC coupling beams under cyclic loading. In the test program, 3 SRC coupling beam specimens are constructed and tested. Through experimental test, the seismic behavior of typical SRC coupling beams was established.

The rate of deterioration in reinforced concrete structures built with Portland cement has increased over the period caused by various factors such as sea wind and environmental pollution. These environmental factors accelerate the corrosion of the reinforcement and the products that formed from the corrosion process generate expansive pressure within the concrete that cause the cracks or delamination on the surface of the concrete. The accelerated corrosion of the reinforcement cause problems in durability of the reinforced concrete by reducing effective cross section of the concrete, reducing cross section of the reinforcement which results in reduced mechanical efficiency of the reinforcement, and reducing internal forces which is caused by reduced rebar/concrete adhesive forces. This research studies the durability of the seven testing samples with variable strength of the concrete and level of corrosion of the reinforcement for reinforced concrete column member and summarizes the results to provide the fundamental basis for evaluating the durability.

When mechanical demolition is performed, the weight of dismantling equipment and the demolition waste of buildings are applied to unexpected load that does not considered during the design of structural member. It is urgently required a structural analysis method to evaluate the safety and the guideline for the appropriate capacity of structural member to support dismantling equipment weight, reflecting the actual circumstance of mechanical demolition. Therefore, the suggested structural analysis method and the guideline for an ability to the loading of dismantling equipment weight can reasonably evaluate the capacity of structural member in demolition, and be used effectively for the increasing efficiency through the proper mangement of dismantling equipment.
