Research On Transforming Multi-story Frame Columns With Diagonal Bracing On The Bottom

Structure transformation is by setting the conversion layer or the use of conversion component will be a structured form of horizontal and vertical load transmission superstructure down. Modern architecture for application of structural conversion has been It is often seen., using structural conversion purpose is generally in order to meet the requirements in terms of building use function, with few exceptions to handle on-site construction in practical construction. Diagonal conversion as a way of converting the structure of the utility model can be widely applied in recent years. From the perspective of the bracing force conversion can be regarded as a special form of truss transfer, can also be viewed as a special form of support. Under horizontal load for eccentric compression column or eccentric tension members, under the vertical load for axial compression members. Model of SATWE software in recent years by three-dimensional truss system model based on the theory of thin-walled column improved upgrade to three-dimensional combination structure model based on the theory of shell element, the applicability of calculating greatly enhanced, is widely used in engineering calculation.The main content of this paper is based on the SATWE software, through the cycle, displacement and internal force of engineering examples comparison scheme selection phase of the analysis, the chevron bracing conversion and X brace conversion research. Analysis and comparison of periodic displacement of herringbone diagonal brace conversion and beam transfer show that monoclinic support will make the irregular plane structure, deflection change of anti lateral force mode, structural torsion is serious; in an inclined strut downward to below ground, the ground plane frame structure rules, clear force, the conversion of two equal. X type bracing conversion and lapping column internal force comparison of Lapping Column shear value is greater, the higher demands on the section, is not easy to meet the requirements of. Internal force analysis of comparative bracing conversion and X brace conversion shows great influence on frame column haunch braces, resulting in complex stress of frame column. On the X type bracing conversion in different structural forms found in the comparative analysis of special-shaped column frame shear wall period, displacement and internal force did not appear abnormal change reverse translational cycle instead of special-shaped column frame, Y direction displacement is obviously too small, in the moment and shear force aspect appears increase phenomenon.Aseismic design of structures is divided into two parts:the seismic checking and seismic measures, they are complementary relationship. Seismic measures are divided into two categories:aseismic structural measures and other seismic fortification measures. "Rigid" is the conversion of frame column, inclined column and beam between them, through seismic measures to make it as a whole to participate in the structure of the force, solves the single scattered component, according to the code standard issue. The number of root of longitudinal reinforcement in non 100% extends into the bearing and the beam longitudinal reinforcement of beam upper lower provisions to a certain extent solved the problem of the joint core shear. In the determination of X type bracing construction scheme of the conversion should be considered when positioning, assembling reinforcement, formwork fabrication and installation, concrete pouring, removal and other factors.
