The bearable lightness of all glass structures

This paper is new developments in structural engineering related especially to the use of the material glass. After a philosophical discussion about why glass is the material for the Future, all glass elements and related techniques are presented from which an all glass building can be assembled. To conclude this paper ,all glass structures like...

Double-curved textile reinforced concrete panels with tensile strain-hardening characteristics

The construction of buildings with fi-ee-form surfaces can be accompanied with relatively high costs. An innovative method to produce free-form surfaces in concrete is the application of double-curved precast panels produced with a flexible re-usable mould technique. Traditional placing of reinforcing bars to strengthen such panels causes...

A completely transparent, adhesively bonded soda-lime glass block masonry system

A pioneering, all transparent, self-supporting glass block facade is presented in this paper. Previously realized examples utilize embedded metal components in order to obtain the desired structural performance despite the fact that these elements greatly affect the facade’s overall transparency level. Undeniably, the oxymoron ‘transparency and...

The use of SCC and textile reinforcement

In an earlier article (CPI issue of August 2011 [1]) a method was presented for producing precast curved panels with a thickness of a few centimeters using the 'flexible mould method'. This method is the central theme in the PhD study of the first author on the realization of freeform architecture in concrete. The concrete panels manufactured...

Concrete shell structures revisited: Introducing a new 'low-tech' construction method using vacuumatics formwork

This paper provides a new perspective on the construction process of concrete shell structures and introduces a new cost saving approach for constructing (single curved) concrete shells using Vacuumatics formwork.

Linear Motion Systems. A Modular Approach for Improved Straightness Performance

This thesis deals with straight motion systems. A modular approach has been applied in order to find ways to improve the performance. The main performance parameters that are considered are position accuracy, repeatability and, to a lesser extent, cost. Because of the increasing requirements to positioning systems, concerning accuracy,...

Magnetic support system

There is described a support system enabling supporting an object such as a platform (1) free from vibration, in that bearing elements (50) have a stiffness (k) which at a working point (z0) equals zero. A bearing element (50) comprises two magnetic couplings (51, 52) provided by permanent magnets (61, 63). One coupling (51) has a positive...
