Dynamic Elasto-Plastic Model for Reinforced Concrete Members

Van der Veen, C. (author), Blaauwendraad, J. (author)

It is becoming increasingly necessary to investigate the strength of reinforced concrete structures subjected to dynamic loading. Experience and knowledge relating to the non-linear dynamic behaviour of such structures is still limited, however. Attempts to solve this type of problems with the aid ofa finite element approach soon encounter...

Underpasses for pedestrians and cyclists: User requirements and implications for design

van der Voordt, D.J.M. (author), van Wegen, H.B.R. (author)

In The Netherlands growing attention is being paid to slow traffic facilities. In order to increase road safety many municipalities build or intend to build underpasses for pedestrians and cyclists. However, such traffic solutions have disadvantages, too. Often people manifest feelings of being fenced in or express fear of violence. Nevertheless...

Phosphorus-31 nuclear magnetic resonance studies of intracellular pH, phosphate compartmentation and phosphate transport in yeasts

Nicolay, K. (author), Scheffers, W.A. (author), Bruinenberg, P.M. (author), Kaptein, R. (author)

31p NMR spectra were obtained from suspensions of Candida utilis, Saccharomyces cerevisiae and Zygosaccharomyces bailii grown aerobically on glucose. Direct introduction of substrate into the cell suspension, without interruption of the measurements, revealed rapid changes in pH upon addition of the energy source. All 3 ~p NMR spectra of the...

Investigation of the stresses in rails: Secondary effects associated with the bending of a centrically loaded rail

Kolvoort, A.J. (author), Woestenburg, T. (author)

The flexural behaviour of a rail under purely vertical load acting in the plane of symmetry is investigated in this paper. For this purpose a rail ofNP 46 standard section was subjected to experimental research with the aid of electrical resistance strain gauges in the Laboratory for Highway and Railway Engineering (Stevin IV), Delft University...

Concrete under Impact Loading, Tensile Strength and Bond

Reinhardt, H.W. (author)

Uniaxial impact tensile tests on plain concrete were carried out with the aid of Split Hopkinson Bar equipment with stress rates of up to 60000 N/mm2. s. Various concrete mixes were investigated under. dry and wet conditions. All the concretes showed an increase in strength with increasing stress rate. At very high stress rates the strength may...
