Dimensioning of Struts for Reinforced Concrete Diaphragm Walls to Secure Excavation of Adjacent Structures
Year: 2025
Type: conference-paper
Abstract: Modern architectural solutions in densely populated areas require structures with multiple underground levels. With advancements in construction technology, numerous solutions have been developed to secure the excavation of foundation pits and adjacent structures. The most rational solution adopted is the securing of the excavation and adjacent structures with reinforced concrete diaphragm walls supported by steel struts at two levels. The paper outlines the specifics of the structural solution, with a detailed analysis of the steel struts. Special emphasis is placed on the stability control of the struts, which was conducted using various methods outlined in Eurocode 3. The control of flexural buckling was performed through the application of the equivalent column method, the use of equivalent geometric imperfections, and the implementation of both geometrically and materially nonlinear analysis with imperfections.
