  1. In this paper, the high - temperature low - cycle fatigue life and fatigue crack propagation life tests are carried on the cylindrical axial symmetry specimens having precrack or non - precrack with different types of notches of 16mnr steel in common use in the petrochemical industry contacting coke drum equipment, the stress / strain and the range of stress / strain of dangerous points are received through stress analysis of the specimens using finite element program under multi - axial stress state. at last, the equations of evaluating the high - temperature low - cycle fatigue life and the fatigue crack propagation life are found through using the least - square regression method

  2. According to elasto - plasticity theory, with the help of finite - method program ansys, the paper undertakes the computer analogue tests about the bearing capacity of pile tip arranged by orthogonal principle, and attains the relations of pile - tip bearing capacity to embedment depth, pile diameter, cohesion, internal friction angle and modulus of deformation. by the means of mathematical statistic, regression equation of the ultimate bearing capacity calculated by finite element method is gained through the regression analysis of 81 group data from the computer analogue tests. by comparison and analysis of the values calculated by finite - element regression equation and the values of in situ loading test, the regression equation is gained which calculates the size effect for base resistance of large diameter pile

    根據彈塑性理論，運用大型有限元軟體ansys按正交設計理論對樁端承載力進行模擬計算，獲得樁端承載力與樁長（埋置深度） 、樁徑、粘聚力、內摩擦角及變形模量等主要影響因素的關系，並採用數理統計方法，對81組ansys模擬試驗結果數據進行回歸分析，得到有限元法確定樁端極限承載力的回歸公式，並將有限元法回歸公式計算值與現場小壓板載荷試驗值進行比較分析，得到大直徑樁端阻的尺寸效應系數計算公式。
  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。
