This equation, which was adopted in CP 117 [2.34,2.35], assumes concrete crushing failure rather than a shear failure of the headed stud. Later, in BS 5950 [2.36], data presented by Menzies [2.46] were used to develop the characteristic shear force resistance Q K. There is no theoretical basis to these data and values given in BS 5950 [2.36

Bamboo reinforced concrete: a critical review SpringerLink

Jul 19, 2018· The use of small diameter whole-culm (bars) and/or split bamboo (a.k.a. splints or round strips) has often been proposed as an alternative to relatively expensive reinforcing steel in reinforced concrete. The motivation for such replacement is typically cost—bamboo is readily available in many tropical and sub-tropical locations, whereas steel reinforcement is relatively more expensive—and
