In the Netherlands, there is a significant housing demand. The Dutch government aims to construct 100,000 houses per year, which presents an enormous challenge. To address this demand and simultaneously tackle the challenge of creating a more sustainable construction industry, ti ...

Parametric Design of Grid Shell Structures

A design method considering semi-rigid joints and stiffness based connection design

The characteristics of the joints play a considerable role in the stability of grid shells. Therefore, the connections are usually assumed to be rigid during the design phase. However, considering the semi-rigid behaviour of connections in the design could be beneficial. This lea ...
The Macaulay method is an integration method used to calculate the force distribution and deformations of a structure similar to the conventional integration method. However, where the conventional integration method requires a new equation for each discontinuity along the beam, ...

Connection Optimisation for Robustness in a Timber Modular Building

A connection optimisation between post and beam timber modules to enable catenary action

To address the increasing housing demand in Europe and simultaneously tackle the challenge of creating a more sustainable construction industry, timber modular buildings present an innovative solution. However, before multi-storey modular buildings become a widespread practice, v ...
Bent up bars were prescribed as shear reinforcement in the first half of the twentieth century, stirrups after the 1960’s. In current Eurocode, bent up bars can be applied again, but restrictions with respect to the maximum shear strength should be followed. Goal of this report i ...
Traditional approaches to noise barrier design often rely on outdated techniques and resource-intensive materials like concrete and steel. However, with sustainability gaining prominence, aligning noise barrier design with green construction principles becomes crucial. Structural ...
Macaulay's method, which makes use of singularity functions to describe external forces on beam structures, is extended for two-dimensional structures. Furthermore an extension on the method of Macaulay is described for singularities in the rotation and displacement field of the ...
The construction industry contributes significantly to global emissions. In response to the growing concern about climate change, new methods are being developed to reduce these emissions. Building with timber is one such approach, as it can be CO2 neutral if reforestation is pra ...
The method of Macaulay utilizes singularity functions to describe discontinuous forces acting on beam structures. This method has been extended to determine internal forces and deformation properties, where the beam is inclined at a certain angle or curved.
Plated girders have been extensively used in steel bridge construction since the 19th century. Over the past century, the effective width method was developed to take the nonlinearities resulting from shear lag and plate buckling into account. This method leads to having a cross- ...
Macaulay's method utilizes singularity functions to describe discontinue forces acting on beam structures. This method has been extended to determine internal forces and influence lines, making use of a single expression. The method can be applied to analyze all possible scenario ...
In the near future, pressure on sustainability requirements in building structures will increase further as governments around the world are forced to tackle climate change issues. The construction industry is one of the most resource intensive and wasteful sectors in the world a ...
Space frame structures today are a common choice of load bearing system for achieving long spans with minimal interruptions of the floor plan beneath. On top of that, the versatility of space frame structures to conform to any shape makes them particularly interesting today, espe ...

Structural Optimization of Stiffened Plates

Application on an Orthotropic Steel Bridge Deck

The orthotropic steel deck (OSD) is a deck system applied regularly in steel bridges all around the world. It consists of a steel deck plate which is stiffened by structural elements placed in two orthogonal directions. The deck plate can be used as an integral part of the struct ...

Transverse load-spread of a voided bridge deck

Comparison between a grillage model and an orthotropic plate model

Orthotropic bridges can be modelled using a grillage model and an orthotropic plate model. The grillage model has some benefits (i.e.: shorter calculation time and easier to apply pre-stressing) compared to the orthotropic plate model. However, during the Blankenburgverbinding pr ...
For railway travel the Insulated Rail Joint (IRJ) is a critical part in most railway safety systems but at the same time also considered a weak link. The IRJ creates a discontinuity in stiffness and geometry that leads to wheel-rail impact forces. The angled IRJ is a proposal to ...
The isostatic slab was developed by Pier Nervi and his colleague Aldo Arcangeli to create an elegant and easy to produce floor system, with efficient use of material. These slabs are designed with ribs aligned to the principal bending stress lines that support a flat deck. Concre ...
Increased traffic loads and ageing of concrete bridges and overpasses in the Netherlands make it necessary to reassess these existing structures. Consequently, the current condition and capacity of many concrete structures need to be evaluated. Residual capacity could be discover ...
Many navigation locks in the Netherlands under management and maintenance of Rijkswaterstaat need to be replaced or renewed in a sustainable way before 2050. In order to achieve this goal, Rijkswaterstaat is planning to renew as sustainable and cost-effective as possible. Most of ...
Piles and pile caps are commonly used in the Netherlands due to the soft shallow subsurface soil that is predominant in the country which does not have sufficient bearing capacity to support heavy structures. Pile caps are currently designed analytically using the strut and tie mod ...
