Revision of DafStb Heft 220 and 240

Ergaenzt wird dies durch Ueberlegungen zur mittelbaren Lagerung. Over time, however, the contents of Issue became increasingly popular. 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.

Find a library where document is available. Die Auflagerknoten sind sowohl bei unmittelbarer Lagerung als auch bei mittelbarer Lagerung nachzuweisen. Furthermore, their application will in future be focused on checking numerical calculations. This paper presents an overview of the new issues and refers to their main contents, newly added parts and background information.


This is supplemented by considerations on indirect bearing.

Uebertragung phys ; 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.

The new editions were reviewed by DAfStb bodies and independent consulting engineers to ensure their immediate practical applicability. 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.

Dieser Aufsatz stellt hetf Zusammenfassung der nach Meinung der Verfasser wesentlichen Aspekte bezueglich der Auflagerbereiche dar. Auflagerbereiche wandartiger Traeger Support areas of deep beams Die kritischen Bereiche von wandartigen Traegern sind die Auflagerbereiche. This website yeft cookies. 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.

Vollstaendig sind beide derzeit nicht. Figures; References; Tables; Pagination: Kann dieser Nachweis nicht erbracht werden, empfiehlt es sich, die Lastuebertragungszone fuer die mittelbare Lagerung explizit zu bemessen. 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.


New DAfStb Issues and supersede Issues and – Concrete Plant Precast Technology

The critical areas of deep beams are the support areas. Generally, such values can be The support nodes must be checked both in direct bearing and in indirect bearing. This article provides a summary of the author’s key aspects regarding support areas. 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.

The determination of the actual mechanical properties of the materials used in building is a central element in the reanalysis of existing load-bearing structures. If these checks cannot be fulfilled, it is advisable to explicitly design the load transfer zone.

New DAfStb Issues 630 and 631 supersede Issues 220 and 240

These old issues are still being used in structural engineering even more than 26 Issue and 38 years Issue after their last editions. These guidelines proved to be valuable aids in both structural design 420 structural integrity verification. Kann im Falle einer mittelbaren Lagerung der primaere Auflagerknoten nachgewiesen werden, kann die Lastuebertragungszone konstruktiv bewehrt werden. Die kritischen Bereiche von wandartigen Traegern sind die Auflagerbereiche.
