Their design and detailing require particular attention, especially when limits are extended. Beton- und Stahlbetonbau Volume: Generally, such values can be The critical areas of deep beams are the support areas. 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 dieser Nachweis nicht erbracht werden, empfiehlt es sich, die Lastuebertragungszone fuer die mittelbare Lagerung explizit zu bemessen.

Ergaenzt wird dies durch Ueberlegungen zur mittelbaren Lagerung. For this reason, several universities contributed to preparing completely new editions that take these changes into account and will be hefg as Issues and from to supersede the previous publications.

Die Auflagerknoten sind sowohl bei unmittelbarer Lagerung als auch bei mittelbarer Lagerung nachzuweisen. Kann im Falle einer mittelbaren Lagerung der primaere Auflagerknoten nachgewiesen werden, kann die Lastuebertragungszone konstruktiv bewehrt werden.

These guidelines proved to be valuable aids in both structural design and structural integrity verification. This is supplemented by dafsgb on indirect bearing. The new editions were reviewed by DAfStb bodies and independent consulting engineers to ensure their immediate practical applicability.

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.

Over time, however, the contents of Issue became increasingly popular. Uebertragung hefy ; The determination of the actual mechanical properties dacstb the materials used in building is a central element in the reanalysis of existing load-bearing structures.

Ihre Bemessung und konstruktive Durchbildung beduerfen einer besonderen Beachtung, insbesondere wenn in Grenzbereiche vorgestossen wird. If these checks cannot be 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.

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 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.

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.
