For homeowners and builders in seismic regions, ensuring the structural integrity and safety of buildings during an earthquake is of paramount importance. This need drives the choice of construction technology, favoring materials and methods that resist seismic forces in active seismic zones.
SYSTEM 3E technology, providing an innovative construction approach, is a promising solution for such environments. The question arises: can SYSTEM 3E technology be used effectively in seismic regions too?
Understanding the SYSTEM 3E technology and its benefits
SYSTEM 3E technology is based on 3E elements characterized by two innovations: a material based on perlite, that makes the SYSTEM 3E the thinnest and warmest single-layer walls in Europe, and a unique shape, making the installation process quick and dry stacking. The system is designed for fast and efficient installation, providing scope benefits including energy efficiency, environmental sustainability, and cost-effectiveness.
The adopted geometry of the Morse taper on the surfaces joining adjacent elements eliminates all degrees of freedom between the adjoining blocks, the finished partitions are characterized by above-average strength and safety. The applied interlocking method, results in construction with physical and mechanical properties governed by the 3E material characteristics. This ensures an even distribution of loads, which is particularly important in seismic vibrations. The absence of weak points in the structure makes buildings more stable and resistant to dynamic forces. This is where earthquake engineering principles are applied to enhance the resilience of structures against seismic activity.
SYSTEM 3E structures are characterized by high durability and resistance to out-of-plane loads, especially those generated by high winds and earthquakes. This is a major advantage in situations, where load-bearing and infilling walls resist vibrations and provide safety after seismic disasters.
Seismic considerations and seismic building codes
The seismic safety of building technologies is regulated by various building codes and standards. In Europe, Eurocode 8 provides a framework for the design and assessment of seismic force-resisting structures considering different seismic zones. While in the US, the International Building Code (IBC) provides similar guidelines for specific locations.
These codes ensure that buildings can withstand seismic loads, categorized according to different seismic hazard levels (low, moderate, high) based on peak ground acceleration (PGA). Seismic hazards must be considered during the design and construction process to mitigate risks and enhance safety in earthquake-prone regions.
Building in seismic regions using SYSTEM 3E - this is what you need to know
Computer simulations on the seismic resistance of SYSTEM 3E indicate that the structures, due to their specific nature, can withstand seismic forces without the need for additional reinforcement such as concrete or steel. More importantly, SYSTEM 3E allows for lightweight yet durable structures to be implemented, which is beneficial in design compliance according to IBC and EC8. Additionally, SYSTEM 3E exemplifies earthquake-resistant construction by utilizing innovative materials designed to enhance the durability and safety of structures during seismic events.
Key aspects of research on the application of SYSTEM 3E in seismic regions
An environmentally friendly and energy-efficient alternative to traditional building methods, SYSTEM 3E was demonstrated to be robust to seismic loads. These tests included static and dynamic analyses using advanced finite element modeling (FEA) and simple and complex micromodels.
To perform the SYSTEM 3E seismic resistance study, several tests and analyses, including both linear and non-linear finite element studies, were carried out to assess the structural behavior of SYSTEM 3E buildings under seismic loads. These analyses also considered the impact of seismic waves generated by tectonic shifts, which travel through the earth and stress structures, particularly through horizontal forces.
Earthquake-resistant 3E technology simulation tests results and conclusions
SYSTEM 3E has been extensively tested, including MacroModel simulations and experimental configurations. For example, with a target displacement of 0.5% and 1.0% drift, the load required to induce such displacements was recorded at 300 and 600 kN respectively. These figures reflect the ability of the SYSTEM 3E structure to absorb and dissipate seismic energy without catastrophic failure. The test results underscore the effectiveness of earthquake-resistant structures in safeguarding buildings from seismic activity.
The shear stresses concentrated in the SYSTEM 3E EO+ structure remained below the characteristic shear strength of the structure, indicating its potential seismic resistance.
The system has demonstrated stability under a variety of static and dynamic loading scenarios, and stress concentration and displacement data indicate a robust response to seismic forces.
Preliminary static analyses have shown that SYSTEM 3E provides structural stability during in-plane loads at levels corresponding to accelerations from 0.05g to 3.0g. This is a wide range, covering scenarios from low to high seismic hazard.
SYSTEM 3E construction in seismic areas - specific design criteria
The design of the technology has been evaluated for different levels of seismic hazard, from low (PGA: 0 to 0.1 g) to high (PGA: 0.4 g and above). SYSTEM 3E has demonstrated the ability to maintain structural stability even under significant seismic forces, making it suitable for areas of moderate to high seismic hazard. Additionally, incorporating seismic dampers can further enhance the resilience of buildings by absorbing vibrations and distributing seismic forces within the structure.
Ongoing and future tests of earthquake-resistant 3E technology
While computer simulations and initial tests have confirmed the potential of SYSTEM 3E technology application in seismic regions, ongoing efforts are aimed at further validating its seismic resistance. We are in the process of conducting more comprehensive experimental testing, including time history analysis and dynamic response assessment, to prove the technology’s application in earthquake-prone areas. Additionally, early warning systems are being tested to provide timely alerts and enhance community safety and resilience planning.
