On the basis of analysis on load,span-depth ratio and distance between rid which is done by WAFFLE,the author find the main factor that leads to the distortion and gives a simple and practical design.

TheFEA results, which agree with the test results, show that the shear resistingmechanism of the beam with span-depth ratio of 1.5 and 2.5 are different: arch actionis significant in beams with smaller span-depth ratio.

The paper also includes the non-linear finite element analysis (FEA) of two testspecimens, with span-depth ratio of 1.5 and 2.5 respectively, using MSC. MARC.

It is suggested that the span-depth ratio of wall-bearing transfer beam should be less than 8 in seismic design, 10 in static design for SRC structure.

The result showed that when ratio of span height was small, transverse shear would impact the bending deflection greatly. However, with the increasing of the creation of span-height, the effect made by transverse shear would decrease , every theory results and numerical results were closed.

A released zone ( L p) of surrounding rock, ground pressure ( P ), surrounding rock strength ( S c) and L p= f(P, S c, K ) a relationship between roadway span height rate K were established with the regressive formula and were certified.

Using the physical model of pile foundations developed by self, a series of simulation test were done. Through analyzing the condition of bearing capacity, it is thought that the roof can be predigested as a simple raise girder to calculate, but must multiply a proper coefficient, when the ratio of span height to breadth height is not too big.

In order to choose the dimension of plane lattice structure scientifically and quickly, the steel consumptions of more than 400 lattice structures with different dimensions and shapes were analyzed. The relationship between the steel consumption and structure dimensions such as span, height, length-to-span ratio, lattice dimensions etc. was discussed.

In this paper, 4 types of stiffening beams including 11 specimens and 2 lintel beams with span to height ratio of 4.6 have been tested under cyclic loading. The results show steel R.

The shear lag effect in frame-tube structures can be neglected when the ratio of beam's span to height increases to some degree,and its behaviors comes close to the behaviors of frame structures.

Shear lag coefficient in framed tube structures was put forward based on the equivalent continuous system method. According to the analysis of the main influence factors on shear lag such as structural height,plane shape,area of corner column,and the ratio of span to height,the valid ways to reduce shear lag were discussed.

Based on the experimental results of 26 unbonded partially prestressed high strength concrete beams under monotonic and low cycle loading respectively,the main factors which influence the deformation and ductility of unbonded beams are studied.

According to the calculation method of the current GB and codes, the formula for calculating the width of the maximum crack of steel fiber-reinforced concrete beams is established, which is connected with those of normal steel fiber reinforced concrete beams and normal reinforced concrete short

The span-depth ratios of coupling beams to interconnect shear walls are generally small, so that brittle shear failure may occur and lead to reduced ductility.

Three series, totaling 16 GFRP reinforced beams with various shear span-depth ratios and longitudinal reinforcement ratios, were tested.

The measurements are described for a fully developed turbulent flow between two rough plates with varying the parameterλz(span/height ratio of roughness elements).

Only enlarged arm span to height ratio and highly arched palate.

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...

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.

The testing of 10 two span R.C. continous deep beams are reported in this paper. Analyses have been carried out by using computer program based on nonlinear finite element method. The distributions of sectional stresses for such deep beams with various span depth ratios are described. The envelop values of internal forces such as elestic moments and shear forces have been calculated and listed in tables. Some formulas for computing flexural strengh of deep beam sections at mid-span or near supports for determining the critical reinforcement ratio and for calculating the load bearing capacity of continous beams are derived. The allowable maximum nominal shear stress has assessed as 0.15Ra. Comparisons between the results of tests and these of calculations are shown good agreement. The moment redistrbution of two span continous deep beams after cracking and at first yeilding of main tension steel bars are studied.
