B a perpendicular to cut the curve in point 6. A line drawn from 

 6 at 45 degrees will intersect the horizontal in point C, where the 

 above process is repeated. The points A, B, C, D, E, thus 

 obtained, are the points at which stirrups are required. 



FIG. 46. 



In the case of uniformly loaded beams, it is only necessary to 

 compute the minimum spacing of stirrups that is, at the 

 support. The spacing at two other points may be obtained from 



the fact that the spacing for a distance from the support is

The diagram of maximum shear intensity along a uniformly 

 loaded beam is shown in Fig. 47. If the shear at the end of beam
