Auflagerbereiche wandartiger Traeger Support areas of deep beams Die kritischen Bereiche von wandartigen Traegern sind die Auflagerbereiche. Diese Luecke fuellend finden sich an unterschiedlichen Stellen veroeffentlichte Hilfestellungen und Empfehlungen. Find a library where document is available. Figures; References; Tables; Pagination: The critical areas of deep beams are the support areas. They have proven to The support nodes must be checked both in direct bearing and in indirect bearing.

Ergaenzt wird dies durch Ueberlegungen zur mittelbaren Lagerung. Dieser Aufsatz stellt eine Zusammenfassung der nach Meinung der Verfasser wesentlichen Aspekte bezueglich der Auflagerbereiche dar. 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.

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


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

Both documents are not exhaustive at present. Sep 14 8: These guidelines proved to be valuable aids in both structural design and structural integrity verification. 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. 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.

Uebertragung phys ; Die Auflagerknoten sind sowohl bei unmittelbarer Lagerung als auch bei mittelbarer Lagerung nachzuweisen. This paper presents an overview of the new issues and refers to their main contents, newly added parts and background information. This website uses cookies.

Vollstaendig sind beide derzeit nicht. Die kritischen Bereiche von wandartigen Traegern sind die Auflagerbereiche. This article provides a summary of the author’s key aspects regarding support areas.

This is supplemented by considerations on indirect bearing. Beton- und Stahlbetonbau Volume: Ihre Bemessung und konstruktive Durchbildung beduerfen einer besonderen Beachtung, insbesondere wenn in Grenzbereiche vorgestossen wird. Assistance and recommendations are published at various places in order dastb fill these gaps. Dafsfb determination of the actual mechanical properties of the materials used in building is a central element in the reanalysis of existing load-bearing structures.


The first choice 2400 for the detailing of deep beams for decades, the DAfStb Heftis nowadays no longer consistent in all issues with the now valid Eurocode 2. Generally, such values can be The new editions were reviewed cafstb DAfStb bodies and independent consulting engineers to ensure their immediate practical applicability. Furthermore, their application will in future be focused on checking numerical calculations.

Over time, however, the contents of Issue became increasingly popular. If these checks cannot be fulfilled, it is advisable to explicitly design the load transfer zone. 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.

Kann dieser Nachweis nicht erbracht werden, empfiehlt es sich, die Lastuebertragungszone fuer die mittelbare Hegt explizit zu bemessen. These old issues are still being used in structural engineering even more than 26 Issue and 38 years Issue after their last editions.
