  1. In addition, in this paper, the calculate results of incremental calculation method and total calculation method are compared ; the infection of the pile stiffness 、 the elastic modulus of soil and pile 、 the excess load 、 the soil character to building enclosure are discussed, and some useful conclusions are found

    另外本文還比較了增量法與全量法計算結果的差異,討論了樁體剛度、樁土彈性模量、地面超載、土體性質等因素對支護結構的影響,得到了一些可供工程參考的結論。
  2. The stiffness matrix is kept constant in all incremental loadings and each iteration. only force vector is changed. so, the efficiency of computing is approved dramatically

    由於採用了常剛度法,則在所有荷載增量與每次迭代中剛度陣均不變動,只需改變右端荷載向量即可,因而顯著地提高了計算效率。
  3. Steel frame with welding joint easily occur brittle collapse because of having a low ductility at joints then , a semi - rigid connected steel frame has large the energy absorption capacity which can resist dynamic loads and the using steel qualities of bracing system and joints are small so adopting a semi - rigid jointed steel frame is economical and stable but for semi - rigid connections are complex and variable , in conventional analysis and design of steel structures , it is usually assumed that the connections between columns and beams are either rigid or pinned the analysis of steel frames adopting the assumption can simplify the procedure of analysis and design , but cannot precisely reflect structural practical circumstance and the errors of calculating results are large , even , get incorrect conclusions semi - rigid connection was referred to in chinese code for design of steel structures ( 2001 , 10 ) , however , it isn ’ t specified how to apply semi - rigid joints in design in fact it cannot be carry out the purpose of the paper give a calculating method that accords practical engineering and easily put into effect worthwhile it is going to promote the development of semi - rigid jointed steel frame in design and heighten structural stability in the paper , at first some commonly employed methods for the modeling of connection behavior are introduced richard abbott function modeling of connection is adopted for extended end plate bolted connection by the 34 test data comparing to regression analysis indicate richard - abbott function modeling of connection represents an excellent fit to test data then after a semi - rigid joint behavior can be modeled as a finite stiffness rotation spring , base on rotation and displacement equation derive the element stiffness matrixes with semi - rigid connections where the effects ofj ointed flexibility geometric non - linearity and shear forces in the connection deformations have been considered in and fixed - end forces are modified finally, a program for calculating semi - rigid with incremental - iterative method has been

    本文的目的就是為半剛性連接鋼框架的設計提供一種既符合工程實際又簡便易行的計算方法,供規范使用過程的補充、延伸或參考;同時,也將促進半剛性連接鋼框架設計技術的發展,為提高結構安全性能、節省工程成本發揮應有的作用。本文首先介紹了常見的幾種應用較為廣泛的樑柱連接彎矩轉角關系模型,在分析比較的基礎上,選用richard ? abbott函數模型作為外伸端板連接彎矩轉角關系模型,通過對34個外伸端板連接的實驗數據與回歸分析得到的參數比較可知,經回歸分析得到的此模型參數與實驗數據符合較好。然後用彈簧表徵連接點的轉動剛度,根據梁的轉角位移方程推導出半剛性連接的剛度矩陣,在單元剛度矩陣中考慮了節點柔性、幾何非線性和剪切變形的影響,並對固端力進行了修正,最後用增量迭代法編制有限元程序進行計算和分析。
  4. The main work and achievements are summarized as follows : based on herrmann variational principle and the nearly - incompressible viscoelastic constitutive relation, a new type of viscoelastic incremental finite element method is presented. in this method, incremental arithmetic is applied to solving the hereditary integrals. it needs less memory space, has simple parameter matrix, and calculates stiffness matrix only once

    主要研究內容如下:從herrmann變分原理出發,基於適用於近似不可壓縮材料的粘彈性本構關系,利用增量法處理遺傳積分,發展了一種粘彈性增量有限元方法,所需存儲空間較少,參數矩陣形式簡單,求解過程只需要形成一次剛度矩陣,適用於藥柱的結構計算,奠定了確定性分析基礎。
  5. When the method of incremental variable stiffness is used in the plastic analysis, the loads are applied sequentially. once the plastic hinge is formed, the loads are increased. so the whole process is divided into many stages

    在塑性分析中主要採用增量變剛度法,荷載是逐級施加的,以每形成一個塑性鉸為分界點,把整個加載過程分成若干個階段
