Assessment of post-tensioning systems for concrete structures
The evaluation of the post-tensioning systems as per ETAG 013 includes not just the elements to place under tension (cables, bars or tendons) but the whole set of components that are needed on site. This "kit" approach means that the analysis must include connectors and couplings, ducts, trumpets and filling materials.
Characterization of the technical performance of a building solution with compressed earth
A manufacturer of a building system based on compressed earth block seeks advice on which which are the most critical technical parameters that have to be tested and documented in order to justify the compliance with the regulatory requirements. This will also smooth both the market entry and the future certification of the product.
Contribution to the drafting of the European Assessment Document for timber building kits
CE marking of timber building kits has been carried out according to the criteria of the ETA Guideline ETAG 007, which was first published in 2001. This has changed with the European Regulation for construction products (EU) 305/2011, which required CE marking to be regulated by a European Assessment Document (EAD). ITeC has contributed to revise this ETAG and develop it into the EAD that the Technical Assessment Bodies of the whole EU will use to evaluate timber building systems based in large, prefabricated elements (walls, floors, roofs) produced in series.
Evaluation of structural reinforcement systems
Procedure for evaluating a system to repair reinforced concrete pillars and walls with structural capacity deficits, covering them with a thin layer of a high strength mortar with added metal fibers. A program of tests and calculation has been defined on the basis of Spanish and European regulations, and it will allow a future certification of the solution.
Assessment of floors built with innovative slabs
Before bringing to the market a building system for composite floor decks that uses lightweight steel panels as floor plates, the manufacturer wants to prove compliance with the regulations, which is far from a trivial issue because the product is out of the application scope of EN 13747 standard. The solution calls for a specific assessment protocol for this system to check if it meets the requirements of the Spanish Building Code and the Spanish Concrete Code.
Evaluation of innovative structural bearings
A manufacturer of bearings for civil engineering structures has introduced innovations in the sliding material, which improve the mechanical performance and durability of the product, but also remove the possibility to obtain the CE mark according to harmonized standard EN 1337-7. ITeC has offered an alternative solution through the European Technical Assessments, that requires to draw a specific testing protocol that must be compatible with the nature of the bearing materials and the evaluation criteria that EOTA has already specified in previous EADs.
Evaluation of concrete additions obtained from the incineration of municipal solid waste
Design of a protocol for assessing the validity of a type II addition manufactured with treated ashes from municipal waste incinerators. It allows to quantify the mechanical, chemical and durability performance that can be expected from different combinations of this addition with CEM II and CEM IV cements that produce concrete mixes as per the EN-206 standard, and also mortars and grouts.
Assessment of industrialized building systems based on steel structures
Definition of an assessment protocol according to the European and Spanish regulatory criteria for industrialized building systems based on modules with a structure of metal profiles to be covered with panels that provide insulation and different finishes. It contemplates performance issues from different sides: structural, fire safety, user safety, thermal and acoustic insulation, hygiene, health, environment and durability.
Evaluation of connectors for expansion joints in concrete structures
The assessment carried out by ITeC is the first ETA issued in Europe for this type of products within the scope of ETAG 030 'Dowels for structural joints'. It includes a method of dimensioning of connectors that ensures the transmission of shear stresses, paying attention to the design of the rebars surrounding the rod housings, and to the fire resistance of these critical points where the slabs suffer a discontinuity to allow expansion.
Evaluation of a foundation kit for light structures
Procedure for assessing a building technique for foundations for temporary or permanent light structures, as per the requirements of mechanical resistance and stability (BR 1) and safety in case of fire (BR 2) of Regulation (EU) No. 305/2011. The calculation of the mechanical behavior has taken into account the physical properties of soil, the depth of the foundation and the dimensions of the steel bars that are driven into the ground.
