CONSIDERATIONS ON THE ADHESIVE TESTING
TYPE’S IMPROVEMENT
The authors of the contribution analyse several types of the specimens, involved in the adhesives’ testing protocol. Based on the results of the Finite Element analysis, respectively of the experimental investigations ones, by means of Holographic Interferometry, they suggest a new type of specimen, which assures a more accurate evaluation of the pure shear effect in the adhesive layer. Also, their original testing stand destined to Holographic Interferometry investigations, described in an earlier contribution, can be efficiently involved in this new type of investigation of the adhesives.
The most critical issue consists of the high-accuracy determining of the shear strength of the adhesive layer, without the bending’s additional effect.
The proposed methodology and type of the specimen offer the adequate answer. The author’s further goal consists in involving this new approach in different kind of adhesives’ examination.

25-86 SOLUŢII PENTRU ÎMBUNĂTĂŢIREA MĂRIRII CAPACITĂŢII PORTANTE A STRUCTURILOR DE REZISTENŢĂ ÎN CAZ DE INCENDII

ACCOMPLISHMENTS FOR THE FIRE RESISTANCE LOAD
BEARING CAPACITY IMPROVING OF THE STRUCTURES
The authors of the contribution presents several possible solutions
destined to improving the load bearing capacity of the steel structural elements.
In this sense, are described some existent solutions, respectively two other
originals, ones. Every solution is analyzed from their usefulness’ point of view,
respectively their limits. The original solutions/proposals seem to fulfil several
major fire safety criteria, mainly to increase the safe period of the structural
elements. The authors intend applying one of them in a forthcoming PhD
thesis experimental part.
Keywords: Steel structures, fire, load capacity, protection against fire
