Dynamic continuous fiber optical strain sensing for damage diagnosis on beam-like composite structures: An experimental and numerical study

The objective of this master project is to improve the current SHM techniques for global damage identification of beam-like composite structures. The studied damage diagnosis method is based on structural vibrations from which the modal parameters are obtained. The literature study provides an overview of the most common vibration-based damage...

Assessing the Impact Damage Risk on Composite Structures: A method of predicting impact damage risk on composite aircraft fuselage by combining probability of detection and a decision risk matrix

Impact on composite structures shows a different damage behaviour compared to metal structures. Due to the current short operational life time of composite aircraft the risks of impact damages on composite structures are unknown. This paper proposes a new method for quantitative risk analysis of low velocity impact damages on composite aircraft...

Development of a preliminary sizing tool forstrategic decision making in composite fuselages using weight and cost optimization

This study is an attempt to develop a preliminary composite fuselage sizing tool for the decision making process utilizing analytical structural analysis equations and a bottom-up cost approach to estimate weight and cost. Previous research by several authors and companies is reviewed in order to define the knowledge gaps that the project is...

Sustainable and circular retrofitting facade: "A future proof panel for building renovation"

The Paris agreement’s mechanisms for 2050 represent a challenge for the world to achieve Net-zero emission and climate resilience. Retrofitting the existing stock is a critical step in every nation to achieve these goals. The building sector has a significant role in the Net-zero emission transition. The ambitions for retrofitting the...

Analysing and improving the applicability of Precast Concrete Sandwich Panels

In this report, the applicability of Precast Concrete Sandwich panels (PCSPs) is analysed and improved. This is done by a multitude of methods: a literature study is performed, an advanced, non-linear Finite Element model and simple linear analytical model are developed, and calculations have been performed on a design-structure from Lievense |...

Assessment of steel-concrete shear connector system with resin injected bolts

The building and construction sector play a key role in achieving a sustainable development. In European countries, buildings are responsible for 40-45% of energy consumption, leading to significant amounts of CO2 emissions. The implementation of reusable structures lead to less waste and harmful emissions to the environment. The main purpose of...

Towards a demountable composite slab floor system

A composite slab consisting of in-situ casted reinforced concrete on profiled sheeting, which is connected to steel beams by shear connectors, is a common structural flooring system in office and multi-storey car park buildings. The headed welded studs, which are most widely used shear connectors, are inexpensive and easy to install because they...
