Abstract : through an example ' s calculation of crack width , the calculation formula adopted by the new and old design specification for hydraulic concrete structures and design specification for concrete structures used in industrial and civil buildings were analysed and compared with each other 文摘:通过实例对新、旧水工混凝土结构设计规范及工业与民用建筑混凝土结构设计规范所采用的裂缝宽度计算公式进行分析比较。
In china code for design of concrete structures ( gb 50010 - 2002 ) , there are no design methods for coupling beams when the depth - to - span ratio is less than 2 . 5 , which is one of the critical problems of the code for design of concrete structures unsolved 并且新颁布的《混凝土结构设计规范》 （ gb50010 ? 2002 ）也没有针对跨高比不大于2 . 5的连梁提出具体的设计方法，小跨高比连梁的设计仍是有待通过试验研究来澄清的问题之一。
22 compressive specimens of high - strength small - sized and 9 shear specimens of behavior hollow - block concrete - masonry are tested , and some formulas tested are not fit for the calculation for high strength concrete - block masonry compared with the code 摘要空心砌块砌体已逐渐代替粘土砖，为研究高强砌块砌体的力学性能，对22个高强混凝土空心砌块砌体试件的受压性能、 9个试件的抗剪性能进行了试验研究，并与《砌体结构设计规范》中的相关公式进行了比较。
The technical specification should be made to pre - pare for pre - stressed reinforced concrete hollow slab design , according to 《 code for design of concrete structures 》 and 《 technical specification of pre - stressed concrete structures with middle strength spiral ribs steel wires 》 根据《混凝土结构设计规范》及《中强螺旋肋钢丝预应力混凝土结构技术规程》 ，编制以中强螺旋肋钢丝为预应力受力筋的空心板的技术条件，为预应力空心板的设计奠定基础。
5 . the formulae that the lately issued code for design of concrete structures gb50010 - 2002 offered are applicable for design of staggered joints , considering joints failure not serous and the difference very little between calculative values and experimental values of staggered joints 考虑到梁中纵筋配筋偏低，节点破坏轻微，节点抗剪承载力计算值与实验值相差很小，故可认为新颁布的《混凝土结构设计规范gb50010 - 2002 》给出的公式仍可用于错层节点的计算。
Moreover , the measured ultimate shear from the tests were compared with that predicted from china design code of reinforced concrete structures , gb50010 2002 , and that from the response2000 , which is based on modified compression field theory by michael collins , both were undertaken before the experiments 文中还将试验实测承载力与我国现行混凝土结构设计规范抗剪设计公式的预测值和基于修正斜压场理论的抗剪分析程序response2000的分析结果进行了对比。
The polymer - geogrid reinforced earth seismic characteristic from the analyse of the fea and the model experiment is a good base of deeply researching polymer - geogrid reinforced earth walls under earthquake and is referable to the preparation for design specification of geogrid reinforced earth walls subjected to seismic loadings 本文通过有限元方法和模型试验分析得出的土工格栅加筋土动力行为特性，为将来进一步研究塑料土工格栅加筋土挡墙的动力行为特性打下基础，并将对制定土工格栅加筋土挡墙结构设计规范地震荷载部分有一定的参考价值。
Make using of the critical point of the arch failure transiting to the tooth failure ( which is also the point when the non - stirrup beam ' s shear bearing capacity arrives to its minimum ) which is advanced in the arch - tooth theory of beams without shear reinforcement by g . kani and the critical point of the diagonal - tension failure transiting to the shear - compression failure which is advanced in the anti - theory , the minimum shear resistance of general bea ms which is destroyed in the range of shear - compression failure is advanced 利用g . kani提出的拱?齿理论中的无腹筋梁的拱齿破坏的分界点(也就是无腹筋粱的最小抗剪承载力点) ，再结合前述理论中所提出的梁剪压破坏和斜拉破坏的分界点，提出了梁在延性的剪压破坏范围内的最小抗剪承载力，并与混凝土结构设计规范gb50010 - 2002比较，结果吻合较好。
At this background , though coupling beams with the small ratio of the span to depth have no sufficient test results , in order to satisfy the needs of engineering design , the code for design of reinforced concrete high - rise structure ( jgj3 - 2002 ) still adopt the design method of decreasing the maximum shear force and increasing the quantity of stirrups . but in china code for design of concrete structures ( gb 50010 - 2002 ) the content of seismic design methods for these kinds of coupling beams continue to be blank 在这一背景下， 《高层建筑混凝土结构技术规程》 ( jgj3 - 2002 )为了满足工程设计需要，对小跨高比连梁在没有充分试验结果的情况下，仍采用降低最大作用剪力和提高箍筋用量的设计方法(虽然这种方法已被国外试验证明在跨高比小于1 . 50的连梁中是肯定不能保证延性要求的) ，而《混凝土结构设计规范》 ( gb50010 - 2002 )则把这部分内容继续留作空缺。
