Maximum bridging

Bridging sites s.s. ring with maximum bridging atoms,... 

At this point, the student should be able to find the "strategic bonds", looking first for all the primary rings, the set of synthetically significant rings, the maximum bridging ring, etc., as explained in Chapter 7. 

Maximum bridge seismic displacement = 6.5 in (with abutment releases)... 

Strength criterion to enable strain hardening with a modest amount of fibres. Eqs 12.9-12.12 outline the quantification of this criterion, which requires that the first crack strength will not exceed the maximum bridging stress of the crack in the characteristic stress-crack opening function. 

An essential element required to meet these criteria is to control the bond strength weak bond will result in low bridging strength and will compromise the first criterion, while bond which is too high will lead to a maximum bridging stress at small crack opening and will compromise the energy criterion.
