Laboratory for Research on Structural Models

Welcome to the website of the Laboratory for Research on Structural Models (LMO). Our lab is embedded within the Department of Structural Engineering at the Faculty of Engineering and Architecture of Ghent University.

LMO staff is specialized in structural analysis, construction, design and testing of metallic and glass structures. As such, we are proud to support the education, research and service to industry of our Department. Feel free to browse our web pages for a first impression, and to contact us for any further information you may like about our activities.

Our mission is to provide high-level research and education and to provide our know-how as a service to industry, especially in the field of structural analysis and construction. More specifically, our most important expertise is focussed at two domains:

steel constructions and structural glass

LMO students and staff build 35 m high ice shell in Finland

Ice ShellBeing part of an international team headed by TU Eindhoven, ten civil engineering students and members of the academic staff of LMO are building a 1:5 replica of the Sagrada Familia in (reinforced) ice in Juuka, Finland. The towers are made using reinforced inflatable membranes sprayed with water and pykrete, forming a rigid shell structure when frozen in cold outdoor conditions. The main tower will reach a maximum height of about 35 m. Throughout the semester, the students have performed intensive background research, material tests and numerical analyses during the course “Spatial Structures” (Prof. J. Belis, ir. J. Dispersyn, ir. K. Martens and ir. B. Vanlancker).

PhD defense by Mr. Marc Vandebroek: Thermal Fracture of Glass, 27/10/2014

mvdb.jpgThermal fracture of glazed façades is a frequent problem with a significant economic impact. It is caused by temperature gradients in the glass panel, e.g. due to solar radiation which causes the exposed central zones to heat up faster than the edge zones which are often covered by a frame. Resulting tensile stresses will lead to glass fracture in case the edge strength is exceeded. As existing (empirical) methods do not provide a sound failure probability and they are not applicable to e.g. double skin façades, there is a need for a more accurate method with a wider scope. To estimate the glass edge strength, a vast experimental campaign was conducted. Subsequently, the influence of climatic and environmental conditions on the glass edge stresses in a double skin façade case was assessed based on real climate data. Finally, also a safety coefficient for thermal fracture was determined.

On July 8, 2014, Bert Van Lancker, assistant at LMO, has won the Young Researcher 1st Place Award during the international GlassConGlobal conference in Philadelphia, USA, with his paper “Rotational Stiffness of Adhesive Connections between Cold-Formed Steel Members and Glass Panels (PDF)”. The prize has a total value of USD 2700.




PhD Defense of Mr Didier Delincé, Experimental approaches for assessing time and temperature dependent performances of fractured laminated safety glass, 31/03/2014

Laminated glass is nowadays a well-known product in the construction industry for conferring safety performances to glazing units. Besides the safeguarding of persons, laminated glass products are contributing to a variety of other safety performances, in case of accidental breakage of one or more of their constitutive glass panes. When they are used in structural applications, the assessment of the residual load-bearing capacities of fractured elements is gaining importance and relevance. Because of the specific properties of polymer materials used as interlayer components, it is necessary to account for time and temperature dependent effects for characterizing their mechanical properties for design purposes by means of experimental investigations. This thesis critically analyses different experimental scales and explains accurately why it is difficult to obtain significant design values, with regard to different types of border effects related to sources of systematic uncertainties. Furthermore it proposes analysis grids to set up more efficient and relevant experimental campaigns, based on test configurations at intermediate scale, relying on the identification of a limited set of critical load transfer mechanisms. The response of interlayer ligaments in fractured configurations is identified as a critical load-transfer mechanism. It is investigated by means of tests on pre-cracked specimens laminated glass according to an incremental approach involving two loading modes and different combinations of temperature and loading level or loading rate. The experimental results allow to identify different failure modes and are giving comprehensive orders of magnitude of the identified time and temperature dependent effects.


PhD Defense of Ms Delphine Sonck: Global buckling of castellated and cellular steel beams and columns, 14/01/2014

doctoraatdsCastellated and cellular members are steel I-section members with round or hexagonal web openings.
Their global buckling behaviour will be influenced by the modified geometry and the effect of the manufacturing process on the already present residual stresses. Current design rules for the global buckling behaviour contradict each other, and so far the effect of the modified residual stress pattern was never considered.
In this work, the influence of the production method of cellular and castellated members on the residual stress pattern is determined experimentally. It is shown that the fabrication process has a detrimental influence on the residual stresses and the corresponding buckling resistance. A residual stress pattern for cellular and castellated members is proposed. Subsequently and the global buckling behaviour is studied numerically.
Based on the results of this investigation, a design rule is proposed, fitting in the Eurocode 3 approach used for the design of steel structures.

The public PhD defense will take place at 17:00 on January 14th, 2014 in the Jozef Plateauzaal, J. Plateaustraat 22, Ghent. More information is provided in the adjacent pdf.
