  1. We research the causes of concrete cracking, develop the high performance anti - cracking additive, optimize the concrete mix and construction techniques, increase the stability of concrete volume by shrinkage compensation, enhance splitting tensile strength, and can meet demand of high workability of fresh concrete. in the study, a thorough investigation of this problem is made from all points of view, with the aid of various modern measurement & testing technology and different theories & methods in surface physical chemistry, structural chemistry, solid - state chemistry, composite materials, fracture mechanics, etc. our research results have shown that the various shrinkage of concrete cause concrete cracking in building engineering, such as autogenous shrinkage, dry shrinkage, temperature shrinkage, plastic shrinkage, carbonized shrinkage, etc

    目前,解決混凝土開裂的方法是綜合的,我們調查研究了混凝土開裂的原因,開發研製了高性能抗裂外加劑,優化混凝土的設計和施工方法,並通過補償收縮達到混凝土體積穩定,提高抗裂強度,滿足混凝土拌和物高工作性能的要求。本研究採用多種測試技術,應用表面物理化學、結構化學、固體化學、復合材料學、斷裂力學等多學科的理論與方法,從不同的角度進行深入的研究和探討。通過調查研究建築工程中出現的混凝土開裂、滲漏問題,發現混凝土在非荷載作用下開裂主要是由混凝土的自收縮、乾燥收縮、溫度收縮、塑性收縮、碳化收縮等各種收縮變形引起的。
  2. The research is presented based on the classical laminate theories for special boundary conditions and few papers have been formulated based on higher - order laminate theories with various cases of boundary conditions. the paper will create the structural - engineering program with mathematica to solve the problem of composite laminated plates based on higher - order laminate theories with various cases of boundary conditions

    目前僅局限於有特殊邊界條件的古典板理論,很少有文章涉到各種邊界條件的高階板理論。本文將利用mathematica的計算環境,編制結構分析程序,在各種邊界條件下,應用多種板理論求解各向異性矩形層合板的振動控制問題。
  3. The appearance of dss in the age of 1970 pushes the decision - making theories into a new developing peak and becomes a new computer - based information systems management tool in the field of systems engineering, management science and ai, which is always used to tackle semi - structural and non - structural information systems decision - making problem

    70年代決策支持系統概念的提出將決策理論推向了一個新的發展高潮,已經成為用於管理的一種新型計算機信息系統並已發展成為系統工程、管理科學以及人工智慧等領域十分活躍的研究課題,常用於解決半結構化和非結構化的復雜信息系統決策問題。
  4. For the structural engineering, the constitutive relations of concrete members under the strength will be nonlinear or elasticoplasticness, in this paper, ottosen constitutive model is adopted, and mohr - coulomb strength principle is selected as destructive principle, the concrete cantilever beam is analyzed by using nonlinear efgm, the calculation result by nonlinear efgm is compared with the analysis software of adina, the comparing proves that efgm used to dissolve the concrete nonlinear problem is feasible

    目前,無網格伽遼金法主要研究都集中在線彈性材料上,在結構工程中,混凝土構件受力后的本構關系為非線性或彈塑性,本文首次在無網格伽遼金法中引入混凝土的ottosen本構模型和莫爾庫侖強度破壞準則,對混凝土懸臂梁等構件進行了非線性無網格分析,並與國際著名結構分析軟體adina的計算結果進行了對比,表明採用無網格伽遼金法解決混凝土非線性問題是可行的。
  5. The structural dynamic optimum design is an advanced subject in the field of engineering structure design at present. the structural optimization problem under dynamic stress and displacement constraints is attached importance

    結構動力優化設計是當前工程結構設計研究領域的前沿性課題,其中的結構動力響應優化(以動位移、動應力為目標函數或約束)近年來受到廣泛重視。
