SE23/24 Shear Design-Eurocode 2Layout 3

The introduction of the Eurocodes for concrete design will alter the way that shear is approached for concrete structures. BS EN 1992-1-11 has adopted the variable angle truss model for shear, a more theoretically consistent approach than that used in BS 8110-12. The model is confidently applied to rectangular sections, but its

Parametric Push-Out Analysis on Perfobond Rib with Headed

In steel and concrete composite structures, it is unfavourable to install many headed studs or perfobond ribs with narrow spacings at the joints. To solve this problem, a new type of a mixed shear connector was developed by combining a headed stud and perfobond rib at the same steel beam flange. In this paper, totally nine push-out tests were conducted. The main purpose was to compare the

Highly-loaded anchor bolts in shear Structural

Jun 02, 2011 · The service load shear force is 32kips to the worst case bolt of an 8-bolt group. The bolts are "through bolts" through an 8" slab with a thick steel plate at both the top and bottom of the slab. The concrete crushing of the bolts in shear will be restrained by the top plate. (The bolts are shear-loaded from the top of the slab.)
