The connection is assumed to be pinned with four bolts outside the column profile. The supporting concrete is to have a grade f ck  = 25 N/mm 2   Thickness Design of Column Base Plate Connections(EC3) FACEBOOK Be the frst of your frends to lke ths Structvlle Engneerng 4,470 lkes Lke Page Ubani Obinna Ranks Ubani Obinna Ranks184 followers Follow GOOGLE+ BADGE Ubani Obinna Ranks  Follow  184 Purpose driven personalityBachelors Degree (B.Eng) iEngineering from Nnamdi Azikiwe UniverPassionate about civil engineering profesexperienced in structural analysis and deView my complete profile ABOUT ME   HOMEFEATURESABOUT USCONTACT USOUR PRODUCTS AND SERVICES  19.03.2018Thckness Desgn of Column Base Plate Connectons (EC3) - Structvlle...http://www.structvlle.com/2017/10/thckness-desgn-of-column-base-plate.html?m=12/4 RECENTPOPULARCO Characteristic force from permanent action G k  = 620 kN Characteristic force from leading variable action Q k  = 132 kN Partial Factor for loads (BS EN 1990 NA 2.2.3.2 Table NA.A1.2(B)) Permanent action γ G  = 1.35 (unfavourable) Variable action γ G  = 1.5 Reduction factor ξ  = 0.925 At ultimate limit state; N Ed  = 1.35G k  + 1.5Q k  N Ed  = 1.35(620) + 1.5(132) = 1035 kN Column Dimensions and Properties  Depth (d) = 209.6mm Width (b) = 205.8mm Thickness of web (t w ) = 9.4mm Thickness of ange = (t f ) = 14.2mm Root radius (r) = 10.2mm Perimeter of section = 1206.4mm Area of section = 76.4 cm 2   Partial factor for resistance   γ m0  = 1.0 γ m1  = 1.25 Base Plate Details  Strength of concrete = 25 N/mm 2  Foundation bearing strength f cd  = α cc f ck / γ c  Take α cc  = 0.85 (for axial compression) γ c  = 1.5 Therefore; f cd  = (0.85 × 25)/1.5 = 14.167 N/mm 2  Area of base plate required A c0  = N Ed  / f cd  = (1035 × 1000)/14.167 = 73057.104 mm 2  Effective Area = 4c 2  + (Section Perimeter × c) + Section Area Enter your email address to subscribe to this blog notifications of new posts by email.

This is shown below; 73057.104   = 4c 2  + 1206.4c + 7640On solving;c = 46.924 mm Check; (h - 2t f )/2 = (209.6 - 2 × 14.2) / 2 = 90.6mm Since 90.6mm > 46.924 mm, there is no overlap between the anges. Thickness of base plate (t p )  t p  = c[3f cd  / (f y γ m0 )] 0.5  t p  = 46.924 × [(3 × 14.167) / (275 × 1.0)] 0.5  = 18.447 mm Therefore provide a base plate of thickness t p  = 20 mm in S275 material (since t p  is less than 40mm). Connection of base plate to column  It is assumed that the axial force is transferred by direct bearing, which is achieved by normal fabrication processes. Onlynominal welds are required to connect the base plate to the column, though in practice full profile 6mm fillet welds areoften used.
