D1.1 Aufgabenstellung Für einen im Spannbett vorgespannten Dachbinder wird der Kippnachweis im Grenzzustand der Tragfähigkeit GZT geführt. Grundlage des Nachweises ist DIN EN 1992-1-1 mit dem nationalen Anhang DIN EN 1992-1-1/NA. Das Beispiel ist in ausführlich behandelt und stellt eine Fortsetzung zu dem Beispiel dar. Die Systemangaben und die Belastungen sind identisch, wobei sich das Beispiel hier auf den Nachweis der Kippstabilität konzentriert. D1.2 Theoretische Grundlagen Der Nachweis erfolgt am verformten System mit einer geometrisch und physikalisch nichtlinearen Berechnung. Folgende…

This verification example deals with the design of a slender pendulum support made of centrifugally cast concrete (see approval Z-15.13-343 [1]) in accordance with the general procedure set out in DIN EN 1992-1-1/NA:2013-04, Section 5.8.6. In addition to the geometric non-linearity of the system according to second-order theory, suitable stress-strain curves incorporating creep effects for concrete and steel must be taken into account in the design (see examples [2, S. 29-35] and [3]).Creep effects may be modelled in accordance with DIN EN 1992-1-1 5.8.6 (3) by assuming a change in shape or…

D1.1Task descriptionFor a roof truss prestressed by a tension membrane, all necessary verifications in accordance with DIN EN 1992-1-1/NA:2015-12 must be carried out for the permanent/temporary design situation in the GZT, with the exception of the stability verification.The stability analysis for this truss is given in Example covered. The evidence in the GZG is illustrated in a further example.D1.2Theoretical foundationsIt is manufactured using the prestressed bed method (prestressing with immediate bonding). It is used in general building construction, primarily under static…

D1.1Task descriptionThe terms of reference have been issued [1] Example 4: Based on a point-supported plate.The flat slab of an office building with lightweight partition walls that are prone to cracking is to be assessed.The following are being examined: the central, edge and corner sections. The columns and the flat slab are monolithically connected. Perimeter and corner columns are positioned flush with the edge of the slab. The column axes form a square grid. This is a non-displaceable system (a building reinforced by wall panels).The office building comprises five storeys, each with a…

D1.1Task descriptionHere is the problem from the DBV collection of examples [1], Example 4: Based on a point-supported slab. The slab internal forces and the required longitudinal reinforcement are covered in EvaDAT Example 0036. For this reason, a detailed problem statement and a repeat of the boundary conditions for the FEM analysis are omitted here; please refer to Example 0036 in this regard: In this example, the punching point on the B/2 axis is examined.The punching shear analysis is carried out, on the one hand, using the load calculated manually from the load application areas from [1]…

The verification example for the fire safety assessment corresponds in principle to Example 10 in [1, S. 10-18 ff.]. For the in-situ concrete edge column of a closed hall (Abb. D1-1) Proof of fire safety measures must be provided:(a) in accordance with the general calculation method [2] Section 4.3, or(b) in accordance with the simplified calculation method set out in [2] Section 4.2 in conjunction with the zoning method described in Annex B.2.It is to be determined which fire resistance class the cantilever support falls into in accordance with the two standards set out in [2] can be…
