Reinforced concrete flat slabs consist of a continuous, thin concrete plate that rests on a grid of columns. The supporting surface of the columns is very small compared to the floor plan dimensions, leading to concentrations of shear forces near the colum ...

Zürich Stadtspital Triemli Personalhäuser – Resource assessment of structural elements

Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer, Julie Rachel Devènes

The Triemli Personalhäuser are three equal 15-story buildings located on the Zürich Triemli Stadtspital campus and erected between 1964 and 1969. Cast-in-place reinforced concrete (RC) slabs and walls form the building cores and their surrounding corridors ...

Flexural behaviour of post-tensioned glass beams: Experimental and analytical study of three beam typologies

Alain Nussbaumer, Pieter Christian Louter, Jagoda Cupac

The concept of post-tensioned glass beams builds on the concrete analogy of the reinforced glass beams. By additionally prestressing the reinforcement in a post-tensioned system, a compressive pre-stress is applied on the glass, enhancing the initial fract ...

Earthquake loss estimation in composite-steel moment resisting frames (MRFs) necessitates a proper estimation of the level of damage in steel beam-to-slab connections. These usually feature welded headed shear studs to ensure the composite action between t ...

The behavior of reinforced-concrete structural elements under moving loads involves many complex parameters related to material properties, vehicle loading, environmental changes and structural response. It is difficult to generate the real conditions of l ...

Taylor & Francis2021

This paper presents the results of 28-month-long monitoring of a slab portion of the Chillon viaducts in Switzerland using strain gauges and thermocouples. This post-tensioned reinforced concrete structure was strengthened with a layer of reinforced ultrah ...

Steel-Concrete Connections by Adhesion, Interlocking, and Friction for Composite Bridges under Cyclic Loading

Jean-Paul Lebet, Dimitrios Papastergiou

This paper deals with of a new type of steel-concrete connection for composite beams. The connection is an alternative solution for steel-concrete composite bridges suitable for prefabrication and fast erection. The composite action of the beam is establis ...

Experimental investigation on punching resistance of R-UHPFRC–RC composite slabs

Eugen Brühwiler, Maléna Bastien Masse

An effective method to strengthen existing Reinforced Concrete (RC) structures is to add a thin layer of Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC), with or without steel rebars, over the concrete slab to create a composite ele ...
