(author)Dynamic testing has grown into a sound method for performance characterization of solar energy components and systems. The power of dynamic data processing was demonstrated before for solar domestic hot water systems. Now, further experience has been gained for solar collectors and heat stores, both small and large in size, for outdoor...report 1997

TNO Bouw (author), van Oosterhout, G.P.C. (author)The paper discusses the effectiveness of stiffening an existing building to improve the dynamic behaviour. The evaluation was part of a Ph.D. studies on the wind-induced dynamic behaviour of tall buildings. Sensitivity analyses by means of a computer model suggested that stiffening tall buildings may not be effective to increase human comfort in...article 1997

TNO Bouw (author), Larbi, J.A. (author), Heijnen, W.M.M. (author)This article presents the results of a microscopic analysis to determine the cement content of five samples of hardened concrete prepared with portland pozzolanic cement and crushed limestone as part of the aggregate. The volume fraction of the coarse aggregate was determined macroscopically from polished plates of the concrete samples. The...article 1997

(author), TNO Bouw (author)ln this paper the authors give their view towards the future wilh regard to stability and the codes. Attention is given to thin-gauge columns sensitive to local buckling, flexural buckling, lateraltorsional buckling and distortional buckling. The phenomena of flexural buckling behaviour of thin gauge columns a¡e described using the results...conference paper 1996

Dekker, K. (author), TNO Bouw (author)Many post-war housing estates, build in the period 1950-1965, are in a derelict state and are unattractive to live in. The housing production in the mentioned pe-riod was very high and in several years more than 15 dwellings per 1000 people. In that time, when the Dutch housing need was high, there were produced more than 80.000 dwellings per...conference paper 1996

Feenstra, P.H. (author), de Borst, R. (author), TNO Bouw (author)A composite yield function is used to describe the behavior of plain and reinforced concrete in biaxial stress under monotonic loading conditions. A Rankine yield criterion is used to monitor the in-plane tensile stresses and a Drucker Prager yield function controls the compressive stresses. A good agreement with experimental data for biaxial...article 1996

(author), TNO Wegtransportmiddelen TNO Bouw (author)This article deals with the experimental verification of the long-term behavior of a periodically excited linear beam supported by a one-sided spring. Numerical analysis of the beam showed subharmonic, quasi-periodic, and chaotic behavior. Further, three different routes leading to chaos were found. Because of the relative simplicity of the beam...article 1996

Stark, J.W.B. (author), Brekelmans, J.W.P.M. (author), TNO Bouw (author)Most current regulations for continuous composite slabs contain rules that limit the application of plastic analysis in the design process. In this paper, results of numerical studies for positive and negative bending and experimental results for negative bending are presented. From these investigations conclusions can be drawn on the...article 1996

Het betekent bovendien dat er ergens lachgas uit het systeem lekt, en dat kost geld. Er wordt veel ontwikkeld om dit probleem uit de wereld te helpen, vooral op het gebied van de closed circuit anesthesie. Hoe staat het er nu voor? Wat kunnen we in de...article 1996
