基础梁、框架梁、柱的纵向受力钢筋连接区域(国外英文资料) Foundation beams, frame girders, and column longitudinal force reinforcing bars The construction of reinforced concrete structures is one of the first of the series With the continuous development of construction, span of framework do more big, the existing steel scale are often not able to meet this need, must be reinforced to connect, to be able to cater to the reinforcement of artifacts. Section 9.4 of the current design of concrete structure design (GB 50010-2002), chapter 9? Section 9.4.1 of the steel bar: The attachment of the steel bar can be divided into two categories: bind and tie. Mechanical connection or welding. The type and quality of mechanical connection joints and welding joints shall conform to the relevant standards of the state. ?? The joints of the stress reinforcement should be set in the lower force. Do not have a joint on the same bar. Hard for the first line of the construction site personnel, have no time to system to study the basic knowledge of mechanics and concrete structure, so, for those parts of the component is stress is relatively small, many people do not know, only know a little bit of fur. In view of this, we have some discussion on this topic by using the information platform of the construction industry. Regional § 1 beam longitudinal reinforcement can be connected The force and deformation of the continuous beam and the upper continuous beam The force orientation of the continuous beam and the upper continuous beam are compared with the stress situation Component name Load direction Support section Across the cross section The upper continuous beam The gravity load is going down vertically The upper tensile Lower tension Continuous foundation beam The foundations counterforce is vertical up Lower tension The upper tensile The frame of the frame is divided into the force under static load The frame of the frame is divided into the area of the area of the internal force in which the horizontal thru
