Consecutively extending such idealization to whole span of a beam may lead to an idealized form of a tied arch having a membrane shear element inside as shown in Fig. 4a, in which the lever arm z varies from z0 at the maximum moment section to 0 at the support section.

The computed stresses can be used to predict intermediate crack-induced debonding near the section of maximum moment.
It is noted that for the beams subjected to other type of loadings rather than direct point loadings, the corresponding arch shape function can be obtained by the same manner above, and it will be the following general form (Kim and Jeong 2011a, b, c): z_{x} = left( {frac{{M_{x} }}{{M_{hbox{max} } }}} right)^{alpha } z_{o} (7 where M max is the maximum moment at a zero shear section.
For the design of SRCFT columns under cyclic loading, reinforcing steel section with the maximum moment of inertia is proposed.
All beams were tested in a four-point bending, because it gives constant maximum moment and zero shear in the section between the loads.
Cortical parameters analysed were as follows: cross section area (CSA, mm), minimum and maximum moment of inertia (Imin, Imax, mm) and mean cortex thickness (CtTh, mm).
By making the end joints rigid, the maximum moment is reduced and moments are introduced at the ends; a smaller beam section can be used and more effectively since more of its length is working nearer its design strength.
Slender steel sections in bending are generally designed by taking the maximum moment as the yield moment.
The model calculates the maximum forces during the tests and the maximum moments in the critical section of the ROPS beams and the attachment moments; and is able to determine the needed steel section of the structure tube, the minimum height of the beams to make rigid the lower part of the structure, and the number, quality and shank diameter of the attachment screws of the ROPS.
