Issue concentrates on guidance and recommendations for determining internal forces for framed structures, slabs, deep beamsSLS verifications such as deformationand various detailed checks such as splitting tensile or edge stresses occurring under partial-area loading.

Vollstaendig sind beide derzeit nicht.

Kann im Falle einer mittelbaren Lagerung der primaere Auflagerknoten nachgewiesen werden, kann die Lastuebertragungszone konstruktiv bewehrt werden.

If these checks cannot be fulfilled, it is advisable to explicitly design the load transfer zone. Kann dieser Nachweis nicht erbracht werden, empfiehlt es sich, die Lastuebertragungszone fuer die mittelbare Lagerung explizit zu bemessen.

Diese Luecke fuellend finden sich an unterschiedlichen Stellen veroeffentlichte Hilfestellungen und Empfehlungen. Sep 14 dzfstb Assistance and recommendations are published at various places in order to fill these gaps.

The critical areas of deep beams are the support areas. Beton- und Stahlbetonbau Volume: Over time, however, the contents of Issue became increasingly popular.

Both documents are not exhaustive dafstbb present. The first choice document for the detailing of deep beams for decades, the DAfStb Heftis nowadays no longer consistent in all issues with the now valid Eurocode 2. Hefts Issue [1] and [2] of the German Committee for Reinforced Concrete DAfStb have been intensively used by engineers in day to-day practice since the first edition.

However, their contents urgently required both alignment with current codes and standards EC2 and incorporation of new findings and fields, such as fire design and numerical simulation. Ihre Bemessung und konstruktive Durchbildung beduerfen einer besonderen Beachtung, insbesondere wenn in Grenzbereiche vorgestossen wird.

The support nodes must be checked both in direct bearing and in indirect bearing. Auflagerbereiche wandartiger Traeger 2440 areas of deep beams Die kritischen Bereiche von wandartigen Traegern sind die Auflagerbereiche. If the primary support node dafetb the nodal strength checks in the case of indirect bearing, the load transfer zone can be reinforced following prescriptive detailing rules.

The determination of the actual mechanical properties of the materials used in building is a central element in the reanalysis hert existing load-bearing structures. These guidelines proved to be valuable aids in both structural design and structural integrity verification. Ergaenzt wird dies durch Ueberlegungen zur mittelbaren Lagerung. Their design and detailing require particular attention, especially when limits are extended.

Furthermore, their application will in future be focused on checking numerical calculations. This article provides a summary of the author’s key aspects regarding support areas.

Die Auflagerknoten sind sowohl bei unmittelbarer Lagerung als auch bei mittelbarer Lagerung nachzuweisen. The new datstb were reviewed by DAfStb bodies and independent consulting engineers to ensure their immediate practical applicability.

Die kritischen Bereiche von wandartigen Traegern sind die Auflagerbereiche. For this reason, several universities contributed to preparing completely new editions that take these changes into account and will be published as Issues and from to supersede the previous publications.

This is supplemented by considerations on indirect bearing. Figures; References; Tables; Pagination: They have proven to
