【摘要】：我國加入WTO以后，國際化進展不斷加快，我國建筑行業(yè)也逐漸擴大了對外交流，不僅越來越多國內(nèi)企業(yè)開始大量承擔涉外工程，國外設(shè)計公司也逐漸進入國內(nèi)市場。由于國內(nèi)外所采用的設(shè)計標準不同，因此在結(jié)構(gòu)分析中，經(jīng)常發(fā)現(xiàn)結(jié)構(gòu)分析結(jié)果有很大差異。而歐洲混凝土結(jié)構(gòu)設(shè)計規(guī)范在歐洲各國及非洲和亞洲一些國家中都有應(yīng)用，是一套通用性、系統(tǒng)性、理論性較強的結(jié)構(gòu)設(shè)計規(guī)范，在業(yè)界具有較強的影響力和先進性，可能成為一套國際標準。因此研究對比中歐混凝土結(jié)構(gòu)設(shè)計規(guī)范異同點，有助于解決涉外工程結(jié)構(gòu)分析中產(chǎn)生的問題，為進一步擴大我國建筑行業(yè)對外交流奠定基礎(chǔ)。 同時研究對比中歐混凝土結(jié)構(gòu)設(shè)計規(guī)范差異，可以全面了解歐洲混凝土結(jié)構(gòu)設(shè)計規(guī)范現(xiàn)狀及該領(lǐng)域國際發(fā)展方向，并在這一認識基礎(chǔ)上，為我國混凝土結(jié)構(gòu)設(shè)計規(guī)范修訂及相關(guān)人員了解熟悉歐洲混凝土結(jié)構(gòu)設(shè)計規(guī)范提供幫助，有助于今后我國混凝土結(jié)構(gòu)設(shè)計規(guī)范的修訂，同時有助于我國混凝土結(jié)構(gòu)設(shè)計規(guī)范與國際接軌。 而EN1992-1-1部分給出了有關(guān)使用標準輕骨料制成的素混凝土、鋼筋混凝土及預(yù)應(yīng)力混凝土制成的結(jié)構(gòu)的通用設(shè)計基礎(chǔ)，以及建筑物的特殊規(guī)定。而EN1992-2除了包含EN1992-1-1部分中描述的大部分內(nèi)容外，還規(guī)定了有關(guān)橋梁設(shè)計的原則與應(yīng)用準則。EN1992-1-1部分中只有極少數(shù)內(nèi)容在EN1992-2中被明確刪除或更改，而其他的所有條款規(guī)定均適用于橋梁設(shè)計。 因此本文主要是將GB50010-2010與EN1992-2進行對比。而且會大量引用我國規(guī)范《公路鋼筋混凝土與預(yù)應(yīng)力混凝土橋涵設(shè)計規(guī)范》（JTG D62-2004）里的條款。 本文的主要研究內(nèi)容如下： （1）對比中歐規(guī)范一般設(shè)計原則及荷載效應(yīng)組合的條款，弄清了我國規(guī)范是采用基于可靠度設(shè)計方法，而歐洲規(guī)范是在可靠度分析的基礎(chǔ)上使用分項系數(shù)方法進行結(jié)構(gòu)設(shè)計的。同時歐洲規(guī)范采用的荷載及荷載組合值系數(shù)均比我國規(guī)范大，歐洲規(guī)范結(jié)構(gòu)設(shè)計更為保守。 （2）對比中歐規(guī)范所采用材料，弄清了中歐規(guī)范在同一混凝土強度等級下，歐洲規(guī)范對應(yīng)的混凝土標準強度、彈性模量、強度設(shè)計值的取值都比我國規(guī)范大，，且中歐規(guī)范非線性結(jié)構(gòu)應(yīng)力-應(yīng)變關(guān)系曲線出現(xiàn)峰值應(yīng)變之前非常接近，在峰值應(yīng)變之后，我國規(guī)范極限應(yīng)變比歐洲規(guī)范大很多，另外歐洲規(guī)范混凝土分項系數(shù)比我國規(guī)范混凝土分項系數(shù)平均大3.33%。歐洲規(guī)范取值更為保守。對比中歐規(guī)范鋼筋特性，弄清了中歐規(guī)范鋼筋品種、規(guī)格比較接近，而鋼筋強度級別有所不同，我國鋼筋是低、中、高級別兼顧，而歐洲規(guī)范沒有低強度級別，偏重于向中、高級別發(fā)展。另外在相同鋼筋級別下，中歐規(guī)范對鋼筋強度取值和彈性模量取值是相同的，而對于鋼筋分項系數(shù)，歐洲規(guī)范取值比我國規(guī)范平均小4.17%。 （3）對比中歐規(guī)范對混凝土構(gòu)件的二階效應(yīng)分析，弄清了中歐規(guī)范可直接通過考慮結(jié)構(gòu)幾何非線性效應(yīng)的分析方法計算，也可在一階分析的基礎(chǔ)上，考慮彎矩增大系數(shù)近似計算。在彎矩增大系數(shù)法中，與我國規(guī)范相比，歐洲規(guī)范的計算方法比較復(fù)雜，計算中還涉及到了鋼筋面積，而且還考慮了一階彎矩中由初始缺陷引起的彎矩。另外我國規(guī)范只考慮有側(cè)移的情況，而歐洲規(guī)范按無側(cè)移和有側(cè)移兩種情況考慮。歐洲規(guī)范在二階效應(yīng)方面的考慮較我國規(guī)范更為保守。 （4）對比中歐規(guī)范非荷載裂縫控制條款，弄清了我國規(guī)范構(gòu)造配筋在梁兩側(cè)，且在箍筋內(nèi)側(cè)，而歐洲規(guī)范的在梁兩側(cè)和下部，且在箍筋之外。另外我國規(guī)范對構(gòu)造配筋和伸縮縫的規(guī)定更為詳細。對比中歐規(guī)范對鋼筋混凝土構(gòu)件荷載裂縫的控制方法，弄清了我國采用裂縫寬度驗算的方法進行控制，而歐洲規(guī)范裂縫控制驗算內(nèi)容較多，包括計算最小鋼筋面積、限制混凝土和鋼筋應(yīng)力、不需進行計算的裂縫控制和裂縫寬度驗算。中歐規(guī)范對于裂縫寬度計算方法較接近。
[Abstract]:After China's entry into WTO, the international progress has been accelerating, and the construction industry in China has also gradually expanded its foreign exchange, and not only more and more domestic enterprises have started a large number of foreign-related projects, and foreign design companies gradually enter the domestic market. Because the design standards adopted at home and abroad are different, the results of structural analysis are often found to be different in the structural analysis. The design code of the European concrete structure has been applied in some countries of European countries and in Africa and Asia. It is a general, systematic and theoretical structure design code, which has strong influence and advancement in the industry, and may become an international standard. Therefore, it is helpful to study the differences and differences between the design codes of the concrete structures in China and to solve the problems arising in the analysis of the structural analysis of foreign-related projects, and to lay the foundation for further expanding the foreign exchange in the construction industry in China. At the same time, the difference of the design code of the concrete structure in China is studied, and the present situation of the design of concrete structures in Europe and the direction of international development in this field can be fully understood, and the basis of this knowledge is also discussed. On the other hand, it is helpful for the revision of the design code of the concrete structure of China and the knowledge of the relevant personnel to be familiar with the design code of the European concrete structure, which is helpful to the revision of the design specifications of the concrete structures in the future, and also to the design specifications and international connection of the concrete structures in China. The rail. And the EN1992-1-1 section gives a general design basis for the structure of plain concrete, reinforced concrete and prestressed concrete made of standard light aggregate, as well as the structure of the building in addition to the majority of the content described in the part of EN1992-1-1, EN1992-2 also provides for the principles and requirements of the design of the bridge Only a few of the contents of the EN 1992-1-1 section are explicitly deleted or changed in EN1992-2, and all other provisions apply to the bridge Beam design. Therefore, GB50010-2010 and EN1992- 2. The comparison is made, and a large number of reference is made to China's Code for Design of the Bridge and Culvert of Reinforced Concrete and Prestressed Concrete (JTG D62-2004). The terms of the article. The principal of this article The contents of the study are as follows: (1) Comparing the general design principle and the load effect combination of China and Central Europe, it is clear that our country's standard is adopted Based on the reliability design method, the European specification uses the sub-factor on the basis of reliability analysis The design of the method is carried out. At the same time, the load and load combination value coefficient adopted in the European specification is larger than that of our country, and the European gauge The structure design is more conservative. (2) The material used in the Central European specification is compared, and the standard strength, elastic modulus and strength of the concrete corresponding to the European specification are clarified under the same concrete strength level. The value of the value is larger than that of the Chinese standard, and the stress-strain relation curve of the nonlinear structural stress-strain relation curve of the China-European standard is very close before the peak strain, and after the peak strain, the standard limit strain of China is much larger than that of the European standard. In addition, the sub-item coefficient of the European standard concrete is more than that of the standard concrete in China. The average of the term coefficient is 3.33%. The value of the European specification is more conservative. By comparing the characteristics of the steel bars in China and the Central Europe, it is clear that the standard steel bars of China and Central Europe are close to each other, and the strength grade of the steel bars is different, and the reinforcement in China is low, medium and high-level, while the European specifications do not have a low strength level, In addition, under the same level of reinforcement, the value of the value of the strength and the modulus of elasticity of the steel bar is the same, and for the sub-item coefficient of the reinforcement, the value of the European specification is greater than that of me. The second-order effect analysis of the structural geometry nonlinear effect can be directly considered by the comparison of the two-order effect analysis of the central-and-European norms on the concrete components, and the first-order analysis can also be based on the first-order analysis. In the method of increasing the bending moment, the calculation method of the European specification is more complicated than that of the Chinese standard, and the calculation method is also concerned with the area of the steel bar, and the first order is also considered. The bending moment caused by the initial defect in the bending moment. No side-shift and side-shift considerations. The European specification is in the second-order effect The consideration of the surface is more conservative than that of our country's specifications. (4) The non-load crack control provisions in China and Central Europe have been compared, and the structural reinforcement of China's specifications is found on both sides of the beam and on the inner side of the stirrups, and the European specification On both sides and in the lower part of the beam and outside of the stirrups. The regulation of structural reinforcement and expansion joint is more detailed. The control method of the load crack of the reinforced concrete member is compared with that of the Central European Standard. The method for checking the crack width of the reinforced concrete member is clarified, and the calculation of the crack control in the European specification is much more, including the calculation of the minimum. The area of the reinforcement shall be limited to the stress of the concrete and the reinforcement. Calculation of crack control and crack width in line calculation
