TheISI association since 2011 has involved companies, engineers, designers and technicians specializing in earthquake engineering in a dynamic and motivated group with the aim of promoting new performance technologies for securing and building new construction while ensuring the high quality standards required by the current NTC.
MTR® System for construction in seismic zones
In an area of high seismic risk, such as Italy's, the construction industry must intervene with useful technologies to minimize the impact of earthquakes on buildings.
The aim of MTR® System is to combine reliability and technology to ensure an innovative and safe solution for projects in these areas. Proof of this is the numerous load tests carried out directly on the construction site and in the various certified university laboratories. The results have certified that MTR® beams, classified as mixed steel-concrete structures, are much higher in performance than traditional AC beams.
In particular, an evaluation of the anti-seismic response was carried out at the UNIBAS (University of Basilicata) testing laboratory by cyclic pseudostatic test with imprinted displacements at increasing drifts on the prototype beam-column made in 1:1 scale.
The conduct of the test showed that:
- The experimentally measured stress values were found to be close, with satisfactory correspondence, to those predicted by the numerical models;
- plastic hinge formation developed near the beam-column attachment section in accordance with the assumptions made in the numerical models;
- the damage mechanism obtained was ductile as evidenced by the high drift values observed;
- The maximum drift value achieved in the experimental phase was 3.5 percent.
Advantages of MTR technology® System for operations in seismic areas and beyond
UsingMTR® Systemperbuild framed structures in seismic zones (and beyond) is an advantage as it ensures:
- Superior performance compared with that of a traditional AC system
- self-supporting elements MTR®
- Lighter structures with less load on foundations;
- Reduced beam sections in height and width;
- Better dimensional ratios within the beam/column node;
- prefabrication to the benefit of speed of execution and safety on site, zeroing out the risks and complexities due to assembly at height;
- fire resistance, without additional cost and processing;
- certain and invariable costs throughout the duration of construction.
