Systematic photoelastic experimental work appears to be scarce and the object of this article is to present for comparison with existing theories the results of three photoelastic tests on simply supported deep beams carrying a central point load.


The formulation is equally effective for very slender as well as deep beams since no assumptions are made regarding such conditions during the formulation.


Optimal topology of trusses or perforated deep beams with rotational restraints at both ends


The primary purpose of this research was to study the effectiveness of bond in deep beams.


The mechanics and behavior of continuous deep beams are briefly discussed from which a strutandtie model for such a beam is developed.

These results provide a reference for the revision of the eode on design of reinforced concrete structures.  作者对钢筋混凝土简支深梁的正截面强度和抗裂度进行了大量的试验,同时又收集了国内外有关这方面的资料进行分析研究,并利用有限元法非线性的计算结果,确定应力图形中受拉区的塑性高度,提出了不同跨高比的深梁的抗裂度塑性系数的计算公式和最小配筋牢,供有关钢筋混凝土结构设计规范修订时作参考。  Based on the nonlinear analysis of finite element and test, the article introduces the behaviour and collapse mechanism of reinforced concete continuous deep beams. It also offers that the reaction of supports of beams varies with the change of spandepth ratio. The maximum moment of the contiuous deep beam exists in span and not at midsupports. The position of tensile region of the section at midsupports goes down as the spandepth ratio reduces. When the spandepth ratio is less than or... Based on the nonlinear analysis of finite element and test, the article introduces the behaviour and collapse mechanism of reinforced concete continuous deep beams. It also offers that the reaction of supports of beams varies with the change of spandepth ratio. The maximum moment of the contiuous deep beam exists in span and not at midsupports. The position of tensile region of the section at midsupports goes down as the spandepth ratio reduces. When the spandepth ratio is less than or egual fo1.0, no point of inflexion appears sometimes. In accordance with the data obtained from the test of 24 reinforced concrete continuous deep beams, the article provides the bending moment and shearing strength formulae and design details. Meanwhile, influence line of various continuous deep beams has been calculated through finite element method for designers.  根据非线性有限元法的分析和试验结果,本文研究了连续深梁的受力特性和破坏机理,并指出连续深梁的支座反力随跨高比的不同而变化;梁的最大弯矩发生在跨中而不是在中间支座;中间支座截面受拉区的位置随着跨高比的减小而下移;当跨高比小于或等于1.0时跨中有时不出现反弯点等现象,按作者所进行的24根连续深梁的试验资料,提出了抗弯强度与抗剪强度的计算式和构造要求,并以有限元法计算了各类连续深粱的影响线,供设计者配套使用。  Oa the basis of availableexperimentaI results at home and abroad the formulas for the calculatioa of the shear strength of reinforeed eortcrete Simpie deep beams under central load are proposed by means of the plastic analysis. Good agreemeat exists between shear streagth predicted by these formulas and test results.  本文在分析国内外已有试验资料的基础上,运用塑性分析方法,求得及集中荷载下钢筋混凝土简支深梁的抗剪强度计算公式。计算结果与原有试验结果及验证试验结果均符合较好。   << 更多相关文摘
