【摘要】：結構轉換就是通過設置轉換層或使用轉換構件將上部建筑的水平及豎向荷載傳導下來的一種結構形式�，F代建筑對于結構轉換的應用已經屢見不鮮,使用結構轉換的目的一般來說是為了滿足建筑使用功能方面的要求,極少數情況是為了建筑實際施工中的現場處理。斜撐轉換作為一種新型的結構轉換方式在近些年得到大量應用。從受力的角度講斜撐轉換可以被看做是桁架轉換的一種特殊形式,也可以被看做是一種特殊的支撐形式。水平荷載作用下斜柱為偏心受壓或偏心受拉構件,豎向荷載作用下為軸心受壓構件。SATWE軟件模型在近些年由基于薄壁柱理論的三維桿系模型改進升級到基于殼元理論的三維組合結構模型,使其計算適用性大大增強,在工程計算領域得到廣泛應用。本文的主要研究內容是在SATWE軟件的基礎上,通過工程實例方案選型階段的周期、位移和內力對比分析,對人字形斜撐轉換和X型斜撐轉換進行研究。人字形斜撐轉換和梁式轉換的周期和位移對比分析表明單斜撐會使結構平面不規(guī)則,抗側力方式發(fā)生偏轉變化,結構扭轉嚴重；在將斜撐下移至地面以下后,地面上框架結構平面規(guī)則,受力明確,兩種轉換相差無幾。X型斜撐轉換和搭接柱的內力對比方面搭接柱的剪力值較大,對截面的要求較高,不容易滿足要求。腋撐轉換和X型斜撐轉換的內力對比分析表明腋撐對框架柱的影響很大,造成框架柱受力復雜。地上x型斜撐轉換在不同結構形式對比分析中發(fā)現異形柱框架-剪力墻的周期、位移和內力并未出現明顯異常,異形柱框架的周期方面出現扭轉代替平動的變化,位移方面Y方向的位移明顯偏小,內力方面彎矩和剪力出現增大現象。結構的抗震設計分為兩個內容：抗震驗算和抗震措施,他們是相輔相成的關系�？拐鸫胧┓譃閮纱箢悾嚎拐饦嬙齑胧┖推渌拐鸫胧��！皠傂杂颉笔强蚣苤�、斜柱和他們之間的轉換梁,通過抗震措施使之作為一個“整體”來參與結構的受力,解決了構件單一分散套用規(guī)范標準的問題。梁下部縱筋非100%伸入支座和梁上部縱筋的根數規(guī)定,從一定程度上解決了節(jié)點核心區(qū)的抗剪問題。在確定x型斜撐轉換施工方案時應考慮定位、鋼筋綁扎、模板的制作和安裝、混凝土澆筑、拆模等因素。
[Abstract]:Structural transformation is a structural form in which the horizontal and vertical loads of the upper building are transmitted by means of a transfer floor or by means of a transfer member. The application of modern buildings to structural transformation has become commonplace. The purpose of the structural conversion is generally to meet the functional requirements of the building, As a new type of structural transformation, inclined brace conversion has been widely used in recent years. From the point of view of force, inclined bracing conversion can be regarded as truss conversion. A special form of. It can also be seen as a special form of bracing. The oblique columns are eccentrically compressed or eccentrically stretched members under horizontal loads. In recent years, the software model. SATWE for axially compressed members under vertical load has been improved from a three-dimensional bar system model based on thin-walled column theory to a three-dimensional composite structure model based on shell element theory, which greatly enhances its applicability. It is widely used in the field of engineering calculation. The main research content of this paper is based on the SATWE software, through the comparative analysis of the period, displacement and internal force of project selection stage, The period and displacement of herringbone oblique brace conversion and beam-type skew bracing conversion are studied. The results show that single skew brace can make the plane irregular, the lateral force mode deflected, and the structure torsion is serious. After the inclined brace is moved down to the ground, the plane rule of the frame structure on the ground, the force of the frame structure is clear, the shear force of the lap column is larger and the section requirement is higher than that of the two types of conversion. It is not easy to meet the requirements. The comparative analysis of the internal forces of axillary brace conversion and X-type oblique brace transfer shows that axillary brace has a great influence on frame column. In the comparative analysis of different structural forms, it is found that the period of frame shear wall with special-shaped column, the displacement and internal force are not obviously abnormal. In the periodic aspect of special-shaped column frame, there is a change of torsion instead of horizontal motion, the displacement of Y direction is obviously small, the bending moment and shear force of internal force are increased, and the seismic design of the structure is divided into two parts: seismic checking calculation and seismic measure. They are complementary. Seismic measures are divided into two broad categories: seismic structural measures and other seismic measures. The "rigid zone" is a frame column, an inclined column and a transfer beam between them. Through seismic measures to participate in the force of the structure as a whole, the problem of the single dispersive application standard of the members is solved. The root number of the longitudinal reinforcement in the lower part of the beam is not 100% and the root number of the longitudinal reinforcement in the upper part of the beam is specified. The problem of shear resistance in the core area of joint is solved to a certain extent. In determining the construction scheme of x type inclined bracing, some factors should be considered, such as location, binding of steel bar, making and installation of formwork, pouring of concrete and dismantling of mould, etc.
