  continuous deep beams
The mechanics and behavior of continuous deep beams are briefly discussed from which a strut-and-tie model for such a beam is developed.
      
The usual design practice for continuous deep beams has been to employ empirical equations, which are invariably based on simple span deep beam tests.
      
Typical cracking behavior of continuous deep beams Deep beams, in general, develop little initial flexural cracking.
      
Given the unique behavioural pattern of continuous deep beams, this practice is unrealiable.
      
Continuous deep beams occur as transfer girders in multi-storey frames, as pile caps and as foundation wall structures etc.
      


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 span-depth ratio. The maximum moment of the contiuous deep beam exists in span and not at mid-supports. The position of tensile region of the section at mid-supports goes down as the span-depth ratio reduces. When the span-depth ratio is less than...

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 span-depth ratio. The maximum moment of the contiuous deep beam exists in span and not at mid-supports. The position of tensile region of the section at mid-supports goes down as the span-depth ratio reduces. When the span-depth 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。

The authors, using the finite element method, analyse the rules of continuous deep beam internal forces under the influence of the support plate width. Meanwhile they study transmission force features that the live load is applied on each support cross-section, and present rational simplified computation model. Also they draw up internal force calculation tables of 2- 5 equal span, different span-depth ratio and every cross-section in continuous deep beams under the action of the live load. The tables...

A general discussion about the finite element method of R/C continuous deep beams is made. Two ordinary cracking models are examined and compared. A new cracking model named mixed model is proposed. The model has the features of both smeared and discrete cracking models. Some elastic supports are introdu- ced to the boundary condition of deep beams.

A general discussion about the finite element method of R/C continuous deep beams is made. Two ordinary cracking models are examined and compared. A new cracking model named mixed model is proposed. The model has the features of both smeared and discrete cracking models. Some elastic supports are introdu- ced to the boundary condition of deep beams. A method of modifying the stiffn- ess of cracking element is suggested. A computation program in FORTRAN77 is made. Some R/C continuous deep beams are analysed with the program. Some experiments of two-span continuous deep beams are made. In the experiments a new method to keep the three supports on a straight line is used. the computati- on results are compared with the experiment results. A conclusion can be made that. the methods used in the analysis are reasonable.
