Planung und Bemessung von WU‐Konstruktionen – Entwurfsgrundsätze und deren statisch konstruktive Umsetzung.

Abstract: <bold>Planning and structural design of water‐tight concrete constructions – basic design principles and their structural realization</bold> In water‐tight concrete constructions, the reinforced concrete structure in combination with planned joint sealings on the one hand and with subsequent crack injections on the other hand is also securing a defined sealing function against water exposure. The utilization demands on water‐tight constructions have been raised significantly over the past years leading in the same degree to higher demands on quality of planning and building processes for these constructions. Present water‐tight constructions are high‐performance structures whose demands on the planning process exceed the common knowledge in architectural and structural design by far. There is general planned about the quality‐regulating, constructive aspects (reduction of constraint stresses, concrete technology and post‐curing) for these structures. But regarding the analytical calculation models for constraint forces, a huge scatter in assumed exposures and resistance as well as a fuzziness of existing models have to be noticed leading to non‐reproductive and blurred calculative design results. This paper is focussing on exposures and resistances as well as on different calculation models leading to practical recommandations for the structural design which is only insinuated in the basic rules for water‐tight constructions.
