On the project

Projekt bude orientován na problematiku konstrukcí kombinovaných z betonu a oceli. Především pak na problémy působení kontaktu mezi těmito a jinými progresivními materiály v různých typech konstrukcí, a o při statickém i dynamickém zatížení. Konkrétně se projekt bude například zabývat problematikou kontaktů lepených kotev, tedy kontaktem mezi kotvou a lepidlem zprostředkovaným lepidlem, při působení dynamického zatížení. Dále se projekt bude zabývat například problematikou kontaktu plechu a betonu ve stropních deskových konstrukcích, tvořených trapézovým plechem s prolisovanými spřahovacími prvky. V takovýchto případech lze kvalitu kontaktu popsat souhrnným parametrem vyjadřujícím pevnost spojení. Tento parametr nazýváme soudržnost.

Description in English
The subjects of the grant project are the problems of bearing structures combined from steel and concrete. The project is closely oriented on the real behaviour of contacts surfaces between the steel and concrete and other advanced materials, in modern, statically or dynamically loaded, structure types. The attention will concentrate for example on the bond quality of bonded anchors (the contact between the steel anchor and concrete performed by glue) or contact between the steel sheet and concrete in the ceiling slab, where the connection is performed by dimples moulded into the steel sheet. In these types of structures the performance quality of the connection can be described by one summary parameter, usually defined as the bond stress.
