Understanding the Basics

While there are rules and standards for varying importance levels and performance categories, compliant solutions have to be designed on a case-by-case basis, considering the many factors in each project which influence compliance.

Due to each building design and each trade needing to comply with varying minimum seismic requirements, it can be challenging for all on site trades, builders, installers and designers to fully understand how to achieve the base level

Importance levels

IL1

• Structures presenting a low degree of hazard to life and other property in the case of failure.

• Farm Buildings, minor storage facilities.

Seismic compliance is never a 'one size fits all'.

requirements to ensure compliance. AS1170.4 is in some areas difficult to interpret.

There are strict performance criteria for each seismically approved product to ensure that certain structures, based on their level of performance, are able to continue to perform during a seismic event. Buildings that fall within importance level three and four are those that ACURA Group have in-depth knowledge of, paired with extensive history of working.

IL2

• Buildings or structures of ordinary occupancy.

• Residential, commercial and industrial buildings. (Except those stated in other categories).

Buildings and structures that:

• Have large numbers of occupants (high-rise offices, sports arenas).

• Shelter persons with limited mobility (Jails, schools, healthcare facilities).

• Support lifelines and utilities important to a community’s welfare.

• Contain materials that pose some risk to the public if released.

Buildings and structures that:

• Are essential to post-earthquake response (hospitals, police/fire stations and emergency communication centers).

• Housing large quantities of hazardous materials.

Performance Categories

ACURA Group partners with highly qualified engineers who will design, and implement seismic solutions into plans and keep projects compliant.

To ensure seismic compliance, all products undergo tension and shear load testing, and if successful, are placed within one of two performance categories: C1 and C2, with C2 holding a more demanding testing regime, thus a higher level of seismic compliance.

Performance Category C1

Maximum crack width of 0.5mm

• Performance stated in terms of strength at ultimate limit state.

• Scope of testing:

- Pulsating tension load

- Alternating shear load

With all this in mind, it is imperative that the supporting documentation is supplied for each compliant product. When partnered with ACURA Group, everyone on site can rest assured that we produce the required documentary evidence to demonstrate the seismic solution we have provided is in fact compliant with the

Performance Category C2

Maximum crack width of 0.8 mm

• Performance stated in terms of strength at ultimate limit state, as well as displacement at damage limit state and ultimate limit state.

• Scope of testing:

- Reference tests to failure

- Pulsating tension load

- Alternating shear load

- Crack cycling and tension load

siFramo Product Specifications

HCP Coating - High Corrosion Protection

All siFramo products come with the high-quality HCP coating as standard.

To meet the most stringent corrosion protection standards, siFramo support system is developed with a new individual multilayer coating, a design which is confirmed as complying with the corrosion category C5-I. This is the highest corrosive category; hence the coating is suitable for industrial fields, involving exposure to high humidity and aggressive environmental conditions.

The perfect system for time-saving screw connection

The siFramo system is assembled via thread-forming tapping screws. The chip-less, custom-fitted cold-work hardening of the female thread means the screw develops form closure and no longer becomes loose. They can also be removed and reused again - excellent for adjustments.

Comparison with torsional moment of inertia lz (cm4). The torsional stiffness of siFramo 80 is approximately 2 to 3 orders of magnitude greater than with open profiles.

Rod Stiffener

When is rod stiffener required?

Threaded rods are designed and manufactured purely for gravity loads. The uplifting forces that come with seismic events easily exceed the dead load on threaded rod, resulting in compressive forces.

Rod stiffeners provide additional support for bracing to prevent buckling of the rods.

The specific needs, sizes, and number of clamps used to attach the rod stiffener angle to the hanger rod required to achieve compliance, is completely dependent on several variables including:

• The hanger rod size & spacing

• Horizontal seismic force being restrained

• Weight of the duct or pipe to be supported

• Seismic restraint installation angle

• Single hanger rod or trapeze supported pipe or duct

Heavy Duty Vibration Restraint

Featured Projects

Royal Adelaide Hospital

“For large and complicated builds, only the best in support solutions will do. We helped to implement the world standard in seismic support at nRAH,” says Simon Joyce, ACURA Group Sales Director.

The Royal Adelaide Hospital spans the equivalent of three city blocks and contains almost 4 hectares of landscaped parks and gardens. What lies beneath the surface is a carefully designed and executed technologically advanced facility - one of the nations best in complex clinical care.

It was therefore a natural fit to be part of the construction process, with ACURA Group supplying the best in innovative seismic approve solutions to this flagship facility.

With services traveling up and down and across 9 levels at nRAH, the support needs of the electrical, HVAC, seismic and fire protection sectors was vast for this $2.4 Billion dollar project.

Seismic compliance became a very large issue on this project and it was necessary to work closely with the electrical, medical gases, plumbing, HVAC, and mechanical contractors to provide a seismically approved and engineered solution.

ACURA Group designed a versatile prefabricated and seismically approved common support frame (CSF), which the contractor built off site. The support frame was then transported in large

sections on-site, lifted by crane (see page 11), and successfully installed across all corridors.

An estimated total of 12km of siFramo was used in this innovative solution, along with other seismic approved products like Zip-Clip and seismic approved fixings.

This innovative solution contributed to fast install times without comprising on compliance.
