  3. At last, with the program, 18 one - storey and one - span prestressed frames are simulated. some conclusions are reached with the taking into account the, secondary moment and types of load applying : ( 1 ) the in the beam affects the ductility of the section and rotary property of the plastic hinge. so total coefficient of the modulation of moment becomes less with the becoming bigger

    最後，本文利用編制的非線性程序，模擬了18榀單層單跨預應力框架，重點研究截面相對受壓區高度、次彎矩、加載方式對塑性內力重分佈和彎矩調幅的影響，從中得出了以下主要的結論和規律： （ 1 ）框架梁相對受壓區高度在很大程度上反映了截面的延性，體現了塑性鉸的轉動能力，框架的總彎矩調幅系數隨著相對受壓區高度的增大而減小。
  4. ( 2 ) if secondary moment is taken for one kind of modulation of moment and there are the same, the effect of secondary moment on the modulation of moment becomes bigger with secondary moment becoming bigger. if prestressed frame can not complete full redistribution of internal force, ultimate load may put off and put up because of secondary moment. total coefficient of modulation of moment also is bigger

    （ 2 ）如果把次彎矩看著是對框架的一種彎矩調幅，在相同的相對受壓區高度下，次彎矩越大，次彎矩調幅作用越強；如果結構不能實現完全的內力重分佈，則次彎矩能夠延緩截面極限承載力的到來，提高結構的極限承載力，結構總的彎矩調幅系數也隨著次彎矩的增大而增大。
  5. 5 ) the secondary moment postpones coming of plastic hinge on frames. in other words, it reduces requisition of rotation ability of section. therefore, it maybe improve modulation ability of frame

    （ 5 ）初始次彎矩的存在，推遲了梁端塑性鉸的出現，也就是說降低了彎矩重分佈對梁端轉動能力的要求，從而有可能提高總調幅能力。
  6. 4 ) as designing, modulation of the secondary moment must be considered. but when the secondary moment is very great, the whole secondary moment as modulation is unfit. there maybe have a fit reducing coefficient

    （ 4 ）設計調幅時，需考慮次彎矩調幅，但當次彎矩很大時，把次彎矩完全作為調幅是不適當的，應當有一相應的折減系數。
  7. At first, this thesis analyzes the main causes in theory, which have effects on the redistribution of internal force and modulation of moment for the bonded post - tensioned partially prestressed concrete frame ( for short prestressed frame ), including the relative height of compressive zone of section ( ), secondary moment and types of load applying. then, this thesis analyzes the test of prestressed frame. then, a method, called curvature - force method, for nonlinear analysis of prestressed frame is put forward

    本文首先從理論上分析了影響后張有粘結部分預應力混凝土框架（簡稱為預應力框架）內力重分佈和彎矩調幅的主要因素，即相對受壓區高度、次彎矩和加載方式等，並初步分析了兩榀只加豎向荷載和兩榀既加豎向荷載又加水平荷載的單層單跨預應力框架靜力加載的試驗。
  8. 2 ) the secondary moment is an important factor on moment modulation. when is small, influence of the secondary moment on moment modulation is small. contrary, when is high, influence of the secondary moment is important

    （ 2 ）次彎矩的調幅作用非常明顯，當相對受壓區高度較小時，次彎矩對調幅的影響作用也小；反之，當相對受壓區高度較大時，次彎矩對調幅的影響作用越大，有時，甚至起控製作用。
  9. By way of these tendons, precest beams and columns can be assembled conveniently, and the joints and frame are monolithic and continuous. consequently, compared with common reinforced concrete frams, this kind of frame systems possess higher reliability and solved the problems in the process of assembling prestressed concrete frames. also it forms the framework of subassemblage and prestressed concrete frames, and explores a new way for industrial production of prestressed structures. by analyzing this system, a series of conclusion are provided, incluing modulation of bending moment produced by vertical loads within beam end, secondary internal forces produced by pretress force, shear resistance of the end of beams, the influence of lateral restrains. theresearch results of this paper are proved to be practical. some advices are also brought forward on the design process

    后張預應力筋既可作為施工階段拼裝手段，又可在使用階段承受梁端彎矩，構成整體受力節點和連續受力框架，克服了裝配式節點受力可靠性差的缺陷，解決了預應力混凝土框架難以裝配的問題，形成預制預應力混凝土裝配整體式框架，開辟了預應力結構工業化生產的新途徑。本文針對預壓裝配式預應力混凝土框架，從豎向荷載作用下的梁端彎矩調幅、施加預應力在框架中產生的次內力、梁端抗剪承載力、考慮側限的無側移框架的承載力分析四個方面對該種裝配式結構體系的性能做了詳細的研究。
  10. 7 ) in the prestesssed frames, direction of secondary moment of horizontal brace and secondary moment of equivalent load is sameness. horizontal brace is stronger, secondary moment of horizontal brace is bigger. 8 ) crack of column has influence on moment modulation on prestressed frames

    （ 7 ）在預應力框架中，一般情況下，橫向約束次彎矩和等效荷載次彎矩同向，它同樣影響總次彎矩的大小，橫向約束越強，橫向約束次彎矩就越大，在次彎矩調幅中所佔的比例就越大。
