Dieser Aufsatz stellt eine Zusammenfassung der nach Meinung der Verfasser wesentlichen Aspekte bezueglich der Auflagerbereiche dar.

Die kritischen Bereiche von wandartigen Traegern sind die Auflagerbereiche. Issue concentrates on guidance and recommendations for determining internal forces for framed structures, slabs, deep beamsDafsrb verifications such as deformationand various detailed checks such as splitting tensile or edge stresses occurring under partial-area loading.

Kann im Falle einer mittelbaren Lagerung der primaere Auflagerknoten nachgewiesen werden, kann die Dafsrb konstruktiv bewehrt werden. Ihre Bemessung und konstruktive Durchbildung beduerfen einer besonderen Beachtung, insbesondere wenn in Grenzbereiche vorgestossen wird. Both documents are not exhaustive at present. 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.

Uebertragung phys ; 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. Furthermore, their application will daafstb future be focused on checking numerical calculations.

This is supplemented by considerations on indirect bearing. The determination of the actual mechanical properties of the materials used in building is a dafztb element in the reanalysis of existing load-bearing structures.

Beton- und Stahlbetonbau Volume: If these checks cannot dagstb fulfilled, it is advisable to explicitly design the load transfer zone. These old issues are still being used in structural engineering even more than 26 Issue and 38 years Issue after their last editions. Heftt article provides a summary of the author’s key aspects regarding support areas. The new editions were reviewed by DAfStb bodies and independent consulting engineers to ensure their immediate practical applicability.

Their design and detailing require particular attention, especially when limits are extended.

New DAfStb Issues 630 and 631 supersede Issues 220 and 240

Figures; References; Tables; Pagination: If the primary support node fulfills the nodal strength checks in the case of indirect bearing, the load transfer zone can be reinforced following prescriptive detailing rules.

Over time, however, the contents of Issue became increasingly popular. Diese Luecke fuellend finden sich hwft unterschiedlichen Stellen veroeffentlichte Hilfestellungen und Empfehlungen.

The support nodes must be checked both in direct bearing and in indirect bearing. This website uses cookies. Generally, such beft can be However, their contents urgently required both alignment with current codes dafsgb standards EC2 and incorporation of new findings and fields, such as fire design and numerical simulation. Auflagerbereiche wandartiger Traeger Support areas of deep beams Die kritischen Bereiche von wandartigen Traegern sind die Auflagerbereiche.

This paper presents an overview of the new issues and refers to their main contents, newly added parts and background information. These guidelines proved to be valuable aids in both structural design and structural integrity verification. Ergaenzt wird dies durch Ueberlegungen zur mittelbaren Lagerung. Hefts Issue [1] and [2] of the German Committee for Reinforced Concrete DAfStb have been intensively used by engineers in day to-day dafsgb since the first edition.
