Reinforced Concrete-Gap-Element against earthquake - experimental and numerical study
In this article it will be shown how masonry walls with arranged notched reinforced concrete beams behave as a typical bearing wall in a masonry building. A special pseudo-dynamic algorithm was developed in order to simulate the boundary conditions of the masonry wall in a building and during an earthquake closely to reality.
A large proportion of damage as well as loss of health and life in earthquake case occurs due to failures on masonry structures. Unreinforced masonry, as common in many countries, naturally has limited resistance to earthquakes because tensile stresses and forces cannot be absorbed as in reinforced concrete and steel structures. For this reason, attempts have been made using various methods to improve bearing capacities of masonry in the case of earthquake. One of these attempts is the use of a reinforced concrete beam with corner notches (Concrete-Gap-Element). In practice, the Gap-Element can be easily connected with use of normal mortar on the concrete slab. The ease of manufacture and application of the Concrete-Gap-Element in masonry walls provide a cheap and simple method for improving the seismic capacity of a masonry building in practice.

Foreword to the Ingenieurbau-Preis 2010
Josef Seiler
INGENIEUR BAUKUNST eV Berlin
"Competitions are figureheads for creatively active and freelance architects and engineers. [...]
As member of the jury which I had the honor of presiding over I was able to experience how difficult it is on one hand to have to make a decision; on the other hand the high level of discussion during the evaluation of the evaluation of each project regardles of the size of the object was an experience in and of itself. I would like to thank all members of the jury wholeheartedly for their efforts. [...]
My congratulations go to the design teams of those five structures that were awarded the Ingenieurbau-Preis 2010. [...]"

BEng, CEng, MSc, MICE, . . . - an analysis of Anglo-Saxon business-cards

Business-cards from business partners often contain a number of abbreviations following the name - especially if the person comes from a country which is either British or characterized as British. This article describes the meaning behind of “Robert Smith BEng(Hons) PhD CEng MICE MIStructE”.
Firstly it is pointed out that academic professions in the construction industry are not directly comparable between Germany and Anglo-Saxon countries, secondly the education and professional development are influenced significantly by professional institutions and, thirdly the abbreviations are either academic degrees or grades of memberships in professional institutions. As an example the education and professional development of a civil engineer and the resulting business-card are described.
Attached are empirical formulas which will enable the far reaching decoding of business-cards from business partners from or related to the construction industry.
