Since the durability depends, among other things, on the quality of the concrete and presence of cracks, it is necessary to calculate the probability of cracking in hardening concrete as reliable as possible in case of durability predictions. In this thesis, it is investigated how the accuracy of stress prediction in hardening concrete can be...

Using of an apparatus for separating magnetic pieces of scrap-material of a first group from magnetic pieces of scrap- material of a second group, wherein a mixture of pieces of scrap-material from the first group and from the second group is collectively transported with a conveyor to a separating zone, in which separating zone the pieces or...

Method for separating a non-ferrous metal-comprising fraction from ferrous scrap, wherein the ferrous scrap is conveyed to a processing device for separating the non-ferrous metal-comprising fraction from the remainder of the ferrous scrap. The processing device supplies a beam of water, and the ferrous scrap is conveyed and released into the...

Moisture is a major source of damage in historic solid masonry. Therefore, control of moisture movement in masonry is instrumental to the durability of masonry buildings. From research and practical experience it is known that many factors may play a role regarding permeability problems in masonry. This paper is focused on materials aspects...

Evaluating and upgrading existing structures becomes more and more important. For a large part of the existing infrastructure and buildings the design life has been reached or will be reached in the near future. These structures need to be reassessed in order to find out whether the safety requirements are met. Not only for new structures but...

In this paper stress concentrations are studied around circular cylindrical openings or voids in a linear elastic continuum. The loading is such that a uniform shear stress occurs in the continuum, which is disturbed by the opening. The shear stress is in the direction of the centre axis of the opening. The stress distribution has been...

Introduction (chapter 1) In analysis software models the infrastructural constructions are often reduced to geometrical linear and surface models (plane stress and shell models). The selection of a model much depends on the speed of the analysis process and the total processing time. The increased computer power has boosted the visualisation of...

A safe design of civil engineering concrete structures must include dynamic loading conditions. However, the knowledge on crack patterns and tensile failure strength of concrete material as a function of the dynamic loading is not sufficiently understood to accurately predict the risks and consequences of accidents. Concrete is a rate-dependent...

We present neutron-scattering results on the magnetic excitations in the spinel compounds Lix[Mn1.96Li0.04]O4 (x=0.2,0.6,0.8,1.0). We show that the dominant excitations below T?70?K are determined by Mn ions located in clusters, and that these excitations mimic the dynamic scaling found in quantum critical systems that also harbor magnetic...

The design of joints to European standard EN 1993 within the semi-continuous/partially restrained philosophy is restricted to steel grades up to S460. With the recent development of high performance steels, the need for these restrictions should be revisited. The semicontinuous joint modelling can be adopted as long as the joint develops...

The present paper describes a numerical formulation for the analysis of damage in steel pipeline bends. In particular, the numerical implementation of Gurson plasticity model is described in the framework of a special element, referred to as “tube element”. This is a three-node element, which simulates pipe behavior combining longitudinal...

The annual production of watery waste streams is significant. Considerable fractions are contaminated and cannot simply be disposed off. They must be stored or further treated. The latter option usually involves a thermal drying step, which renders the residue suitable as a resource: 1. Sludge with high organic content can serve as biofuel. 2....

The research presented in the thesis contains a part of the ongoing effort to improve the situation of the Dutch construction sector. For at least the last decade, a number of measures known as integrated contracting has been heralded as the solution for many problems in the Dutch construction industry. One of the main reasons for integrated...

The Dutch national energy company Eneco is in the process of implementing a large project involving the storage of gas in salt caverns in Epe, Germany. For short-term gas trading and flexibility in the gas market Eneco intend to lease two caverns till 2030 with an option to lease till 2060. Salzgewinnungs Geselschaft Westfalen (SGW) leaches the...

The automated approximation of solutions to differential equations which involve discontinuities across evolving surfaces is addressed. Finite element technology has developed to the point where it is now possible to model evolving discontinuities independently of the underlying mesh, which is particularly useful in simulating failure of solids....

Energy transfers within large-eddy simulation (LES) and direct numerical simulation (DNS) grids are studied. The spectral eddy viscosity for conventional dynamic Smagorinsky and variational multiscale LES methods are compared with DNS results. Both models underestimate the DNS results for a very coarse LES, but the dynamic Smagorinsky model is...

The variational multiscale method has been shown to perform well for large-eddy simulation (LES) of turbulent flows. The method relies upon a partition of the resolved velocity field into large- and small-scale components. The subgrid model then acts only on the small scales of motion, unlike conventional LES models which act on all scales of...

In the design of low-rise buildings, wind tunnel experiments are scarcely employed to assess the wind-induced pressures, which are required e.g. for the simulation of ventilation flows or for the evaluation of the structural integrity. Instead, techniques are used, which predominandy rely on inter- or extrapolation of wind pressure coefficients,...
