During verification, the software applies the following code regulations: steel code for members EN 1993-1-1 steel code for connections EN 1993-1-8 concrete code EN 1992-1 CEB (COMITE EURO …Blow-out failure is checked for headed anchors (Anchor type – washer) with edge distance c ≤ 0.5 hef according to EN 1992-4, Cl. 7.2.1.8. Anchors are treated …4. When reinforcement is used to restraint concrete breakout, the overall anchorage design should ensure that there is sufficient strength corresponding to the three other failure modes described in the Introduction (pullout failure, side-face blowout failure, and pryout failure). The three failure modes will be addressed as follows: a.Below is an example of some Eurocode Base Plate Calculations that are commonly used in base plate design. Often when designing base plates, we will consider a few different checks relating to the various components of a base plate, namely: The Concrete base – generally checked against bearing and compression forcesBearing failure in concrete should be thought of as a crushing failure, while shear failure is a diagonal tension failure. AHaddad1 (Structural) 15 Jul 09 05:31. hokie66, There are three types of concrete failures. 1) Diagonal Tension Failure in Long Span Beams. 2) Shear Compression Failure in Short Span Beams. pets for homes ayrshire A bolt subject to design tension force in Steel Base Plate Design is designed according to EN 1992-4 – Cl.7.2.1.3 and shall satisfy: N Rk,s =c×As ×f uk N R k, s = c × A s × f u k and N Rd,s = N Rks γMs N R d, s = N R k, s γ M s where: c c = reduction factor for cut thread.
