RC Design 2 (Eurocode)

The next step after RC Design 1 (Eurocode): flat and post-tensioned slabs, walls, corbels and nibs, staircases, crack width and deflection by calculation, and slabs on grade, to EN 1992-1-1 with EN 1990 combinations, each with a STATIX concrete calculator on its Eurocode 2 route.

Lessons

Lesson 1Flat slabsThe equivalent frame of Annex I, load arrangements, column and middle strips, moments at edge columns, punching to 6.4 with links, span/d and detailing. Lesson 2Post-tensioned slabsUnbonded tendons: load balancing, the losses of 5.10, stresses at transfer and in service, ULS bending, punching with the prestress, and which checks follow ACI 318-19. Lesson 3RC walls and slender wallsWalls as members (9.6), effective length and slenderness against λ_lim, imperfections and nominal curvature, the end strip, in-plane shear by 6.2, steel limits and cover. Lesson 4Corbels and nibsThe strut-and-tie model of Annex J.3 and 6.5, nodes and the tie, the horizontal force, anchorage, links by J.3(2) and J.3(3), bearings by 10.9.5, and continuous nibs and half joints by hand. Lesson 5StaircasesStairs as one-way slabs, the effective span with landings, actions on plan, bending, shear and span/d of the waist, the bars at the kinks and re-entrant corners, cover and fire, and dog-leg stairs on landings that span across. Lesson 6Crack width and deflection by calculationThe quasi-permanent load and the limits of Table 7.1N and 7.4.1, minimum steel and the tables of 7.3.3, crack width by 7.3.4, deflection by 7.4.3 with tension stiffening, creep and shrinkage, and when a member counts as cracked. Lesson 7Slabs on gradeGround-bearing slabs with EN 1992-1-1 materials on Meyerhof’s yield lines and Hetenyi’s beam on springs: the subgrade modulus, rack legs at the interior, joints and crossings, punching to 6.4, storage, minimum steel, joints and cover.

Who it is for

Students and graduate engineers who have done a first course in reinforced concrete to the Eurocodes.
Engineers moving from beams and columns to whole floors and special members on Eurocode projects.
Engineers who know the SA code: every lesson links its twin in RC Design 2.

Before this course

It builds on RC Design 1 (Eurocode) (bending, shear, span/d, columns, two-way slabs, footings and punching, detailing) and does not repeat it.

Which values the lessons use

EN 1992-1-1 leaves some values to each country’s national annex. The lessons follow the calculators’ Eurocode 2 route: EN 1990 equation 6.10 with the recommended factors of Table A1.2(B), the imposed loads of EN 1991-1-1, and the recommended values of EN 1992-1-1, except α_cc, which is 0.85 for bending and axial load and 1.0 for shear (the PT slab page of lesson 2, the RC wall page of lesson 3, the corbel page of lesson 4 and the staircase page of lesson 5 use the recommended 1.0; the lessons say so). Each lesson says which values it uses, so you can compare them with your own country’s annex. The SA annex (SANS 51992-1-1) is a separate route on the calculators. The post-tensioned slab page adds the flat-slab rules of ACI 318-19 on its Eurocode 2 route; lesson 2 says which checks follow them. EN 1992-1-1 has no clause for slabs on grade: the slab on grade page of lesson 7 joins EN 1992-1-1 materials, punching and cover (with α_ct 1.0) to published yield-line and beam-on-springs theory, and lesson 7 says which checks follow which.

The STATIX tools it uses
