Strengthening Haussmannian and Ski Resorts Hotels Wall Openings with Steel Beams and Steel Portal Frames
Strengthening Haussmannian and Ski Resorts Hotels Wall Openings with Steel Beams and Steel Portal Frames

Summary/Abstract: Existing structures must be adapted to comply with current standards or for space efficiency requirements. This adaptation may include the need to create openings in existing walls. In load-bearing walls, the introduction of openings modifies locally the loading path, therefore the opening needs to be strengthened. Several strengthening techniques can be applied. In this paper, two strengthening practice solutions, based on the introduction of steel beams and steel portal frames currently applied in Haussmanian buildings and French Alps Ski resorts hotels, are described. Those practice solutions can be applied to openings in walls with different materials and thicknesses and for a high variety of loads, presenting acceptable results along time. The knowledge presented in this work is intended to give guidance to strengthening guidelines definition and at the same time to support and encourage the development of innovating strengthening techniques.
