本文以軍用機場地面單機掩蔽庫工程建設為工程背景，首次對內襯三維波紋鋼板混凝土拱型復合結構的受力機理進行了靜力、動力和爆炸荷載的分析研究。根據將橫肋、鋼筋及三維波紋鋼板的作用均勻分佈在殼體范圍內的情況，忽略橫肋、鋼筋及三維波紋鋼板沿殼體母線方向的抗拉、抗彎及其抗扭作用，首次推導出了內襯三維波紋鋼板混凝土殼體的微分平衡方程，建立了有限元計算模型，並採用三角函數法，求解了三維波紋鋼板混凝土拱型復合結構在分佈荷載和集中荷載作用下的位移響應和應力響應，並與普通殼體進行了比較。On basis of the character of the structure at the stage of construction, the stress balanced method was developed to decided the forces of cables and the stresses of the arch rib sections, which is according to the normal stress controlling conditions on the top and bottom of arch rib section and considering the influence matrix
針對這一受力特點，本文根據拱肋截面上、下緣應力平衡條件及影響矩陣的概念，發展了應力平衡法，用以確定拉索的合理索力，從而使拱助結構受力合理並具有理想的線形。The paper build a plane model of the whole bridge based on the fem, and analyze the internal force and structural displacement changes in every damage circumstance. the data reflect that the damages in arch rib in the tip will make internal force of some sections increased, accordingly the stability and the durability of the structure reduce ; the damages in the arch foot will change the structure system ; and the displacements of abutments will develop great accessional internal force, and deform the main arch and even crack, accordingly change the system of the structure
論文建立了全橋的平面有限元模型，分析了在各種病害情況下全橋的內力及結構位移的變化，計算數據反映了，拱頂拱肋損傷會造成某些截面的內力增大，結構的穩定性和耐久性降低；拱腳損傷可能引起結構體系改變；墩臺位移會使上部結構產生較大的附加內力，使拱圈變形甚至於開裂，從而導致結構的受力體系發生改變等。Based on the above deduction, the numerical solution of the condensation heat transfer coefficient outside horizontal tubes with annular fins is obtained
在此基礎上，推導出水平環肋管在數值解法下的管外冷凝表面傳熱系數理論值的計算公式。In this paper, load carrying mechanism, lateral displacement, and design and calculation procedure of lightweight frame structure of multi - ribbed wall panel are studied with chief achievements as follows : based on the test, which a ten - story building model of lightweight frame structure of multi - ribbed wall panel with ratio 1 : 3 is studied though the pseudo - dynamic test, the wall is considered as a plane compound substructure, and space frame - plane compound substructure computational finite element model is given
本文就密肋壁板輕框結構在彈性階段的受力機理、設計計算方法及側移進行了探討。主要完成下列工作：在10層密肋壁板輕框結構1 / 3比例房屋模型擬動力試驗研究的基礎上，將墻板視為平面復合子結構，建立空間框架? ?平面復合子結構有限元分析模型，對1 / 3比例房屋試驗模型進行數值分析。3. as for side web girder, the principle of minimum potential energy has been introduced. by assuming different displacement function, the force and stress formulae for flanges under uniform loading, horizontal axial force, or vertical concentrated force have been derived
對于邊主肋截面主梁，本文介紹了能量變分法，通過假定板不同的軸向位移函數，推導了懸臂梁在均布荷載、水平軸向力、豎直集中力作用下的微分方程和應力計算公式。分享友人
