Proposed Panel Zone Model for Beam-To-Column Joints in Steel Moment Resisting Frames

Dimitrios Lignos, Andronikos Skiadopoulos, Ahmed Mohamed Ahmed Elkady

In capacity designed steel moment resisting frames (MRFs), beam-to-column joints (i.e., panel zones) are designed to remain elastic. To potentially exploit the beneficial aspects of the stable panel zone hysteretic response in shear, a robust panel zone mo ...

Origami-inspired carbon fiber-reinforced composite sandwich materials - Fabrication and mechanical behavior

Thomas Keller, Yuntong Du

A folding fabrication method inspired by origami for carbon fiber-reinforced composites to fabricate three-dimensional structures is presented. PMI foams serve as substrates, making it possible to manufacture this kind of origami-inspired composite sandwic ...

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 ...

Design and Manufacturing of an Electrostatic MEMS Relay for High Power Applications

Yves Perriard, Yoan René Cyrille Civet, Christian Köchli, Florian Louis Copt

This paper addresses the design and manufacturing of a crab-leg based MEMS relay for a high power application. Thanks to a contact resistance lower than 100 mΩ, the relay can hold a current in the order of magnitude of an Ampere without further thermal lim ...

A "combi-encapsulant" for enhanced performance of glass-free lightweight crystalline silicon solar PV modules

Christophe Ballif, Alessandro Francesco Aldo Virtuani, Fabiana Lisco

Lightweight crystalline silicon (c-Si) PV modules with a weight of 5kg/m(2), by substituting the typical front glass with a thin polymer sheet and the standard back sheet by a composite sandwich structure are presented here. With this work, we propose the ...

Cold stiffening of orthotropic steel decks by a composite UHPFRC layer

Eugen Brühwiler, Lan Duan, Shichao Wang

Cold stiffening of the plate of Orthotropic Steel Deck (OSD) of bridges can be achieved by adding a layer of Ultra-High Performance Fiber Reinforced Cementitious Composite material (UHPFRC) on top of the deck plate by composite design, thus expecting to re ...

Thermomechanical characterization of a balsa-wood-veneer structural sandwich core material at elevated temperatures

Thomas Keller, Anastasios Vassilopoulos, Chao Wu, Niloufar Vahedi

The tensile, compressive and shear behavior of standardized specimens cut from a veneered balsa wood used as structural sandwich core was investigated at ambient temperatures of up to 250 degrees C. The average moisture content was 9.1%. The specimens' res ...

Two-dimensional quasi-static debonding in GFRP/balsa sandwich panels

Thomas Keller, Anastasios Vassilopoulos, Aida Cameselle Molares

The two-dimensional (2D) debonding behavior of GFRP/balsa sandwich panels presenting embedded circular disbonds at the face sheet/core interface was experimentally investigated. The bottom of the panels was fixed and out-of-plane quasi-static tensile loads ...
