  1. Partially prestressed concrete structure has been widely used in the field of civil engineering. the deformation is very important for prestressed concrete members, for they are thinner than those of reinforced concret owe to the adoption of hign - intension material and developed technic of design and construction. at present, there are some formulae for deformation in the criterion of many countries. mostly there are 3 methods in use : double linearity method, method of valid inertia and curvature integral calculus method. this article will discuss the influence of material, spa, construction form, and adjust the formula for stiffness of gb50010 - 2002 to a new uniform formula for deformation

    在土木工程領域，部分預應力混凝土結構因其良好的跨越能力和經濟性而得到了廣泛的應用，並發揮了巨大的作用。由於採用了高強度材料並進一步改善了設計和施工技術，預應力混凝土構件一般比普通鋼筋混凝土構件更為細巧，因此，撓曲變形問題顯得尤為重要起來。目前，各國規范對于部分預應力混凝土構件的變形計算均有相應的公式，變形計算的關鍵是剛度的計算。
  2. Are uncertain and should be regarded as random variables, therefore the reinforced concrete frame is stochastic structure inherently, and then its motive equations converted to combined random differential equations for the uncertain parameters and external random excitation. these equations were solved by order - orthogonal expansion method with pseudo - excitation method, and then the statistic stochastic responses of random structure were obtained. at last, based on the stochastic cumulative damage model with double parameters developed by park, formulas were formulated for calculating structural earthquake damage probability using the structural reliability theory ( mainly jc algorithm ) in extensive random space

    首先對受地震激勵的剪切型鋼筋混凝土結構進行建模，用隨機等效線性化方法將二階非線性微分方程組化成一階線性微分方程組（或稱之為狀態方程） ；再考慮材料等參數的隨機性，則狀態方程成為復合隨機微分方程組，將擴階系統方法和虛擬激勵方法推廣並應用於這個復合隨機微分方程組，求出結構的隨機響應量的統計參數；最後採用隨機累積損傷破壞準則，在廣義隨機空間內，用jc演算法求解失效概率，進而求出結構的抗震可靠度。
  3. In the paper, the latticed shell of double - layer hyperbolic pyramid is vertically applied to the structure of cooling tower and reinforced concrete planks with ribs are put up around the latticed shell, in accordance with situation that the most latticed shells are applied to lateral roof and cooling tower is put up by the reinforced concrete structure, a kind of new construction that includes the lower reinforced concrete structure and the upper latticed shell structure is established

    本論文把雙層雙曲線四角錐網殼結構豎向應用於冷卻塔的筒壁，在網殼的周圍掛鋼筋混凝土帶肋板。由於目前大多數網殼結構都水平應用於屋蓋或樓蓋結構和冷卻塔筒壁大多數採用鋼筋混凝土結構，本文的研究形成了一種上部網殼結構下部鋼筋混凝土結構的新型結構。
  4. Because width of rib is larger than before, we can change single - rib beam to double - rib beam. stability in transportation and aethetic effectiveness is improved. in this article we make the example of 20m - span simple - supported reinforced concrete beam - bridge

    肋寬增大后可以從截面形式上作適當的改變，改單肋為雙肋，這樣既達到美觀的效果又增強了梁在運輸施工過程中的穩定性。
  5. Demolition of a reinforced concrete double - curvature arch bridge by controlled blasting

    鋼筋砼雙曲拱橋的控制爆破拆除
  6. Based on the characters of structure of the project, the structural style selection is given and analysis program of the latticed shell of double - layer hyperbolic pyramid cooling tower is programmed by the finite element theory and vb 6. 0 advanced programming language, which includes of 15 programs and directly aims at cooler tower and gives the forcing property by the computing program of the latticed shell of double - layer hyperbolic developed. analysis of static stress and temperature stress is given out by means of three dimens ions members finite element and numerical analysis, optimum design of member sections is given out by full stress, analysis of geometric nonlinear is given out by nonlinear finite element, analysis of earthquake stress is given out by the mode decomposition response - spectrum method, the latticed shell cooling tower compared with the reinforced concrete structure finally

    該軟體包括15個程序，其針對性強，直接針對冷卻塔，對該結構進行了受力分析，具體分析包括：採用空間桿件有限元和數值分析方法對結構進行了靜力分析與溫度應力分析；採用滿應力法對應用於冷卻塔的桿件截面進行了優化設計；採用非線性有限元分析方法，並利用荷載增量法對該結構進行幾何非線性分析；採用振型分解反應譜法對網殼的自震特性及地震反應作了一定的研究；並且將具體工程的研究結果與鋼筋混凝土結構冷卻塔進行對比。

  8. By contrast, the effect of improving the adhesive mode of cfp, that is to say, epoxy - bonding double carbon - fiber composite plates or epoxy - bonding u shape cfp anchorage is less notable. the loading - bear capacity of double cfp reinforced concrete beams is 8. 5 - 11. 3 percent higher than that of the single cfp reinforced concrete beams ; the loading - bear capacity of epoxy - boding u shape cfp anchorage reinforced beams is 4. 7 - 18 percent higher than that of the single cfp reinforced beams

    相比之下，改善碳纖維板的粘結方式，即採用粘結雙層碳纖維布和在單層碳纖維布的基礎上粘結u形包頭的影響要小一些：採用雙層碳纖維布加固比單層碳纖維布加固時的極限承載力提高了8 . 5 % - 11 . 3 % ；採用包頭形式加固比單層碳纖維布加固的極限承載力提高了4 . 7 % - 18 % 。
