Connections should therefore be clearly detailed in the design phase to make certain that both contractors and building inspectors comprehend project specifications. Firm, well thought out specifications are the best way to ensure that the designed product is the one that is actually used. Seismic-relevant non-structural applications Anchors are often used to fasten non-structural components. Their design and selection is therefore crucial in terms of minimizing both injuries to building occupants and the costs associated with seismic events. As fire is a common byproduct of earthquakes, firestop systems should be specified in accordance with their ability to withstand extreme deformation.

Anchors subject to this new test procedure must now incorporate in the ETA all the required seismic design technical data . The suitability for seismic loading is classified as: ETA seismic category C1 – similar to U.S. pre-qualification procedure; only suitable for nonstructural applications according to the EOTA TR045 recommendations ETA seismic category C2 – arduous seismic crack movement tests qualify an anchor as suitable for more demanding structural and non-structural applications Structural applications Acceleration (ag.S) Non-structural applications Building importance II, III, IV < 0.05g non-seismic 0.05g to 0.1g ETA C2 > 0.1g Acceleration (ag.S) Building importance II, III < 0.05g Building importance IV non-seismic 0.05g to 0.1g ETA C1 > 0.1g ETA C2 ETA C2 Adapt locally The map above is based on national earthquake data (for ordinary buildings and ground type A) and provides perspective on the relevance of the new ETA guidelines in various countries.

This code is in full compliance with the standards in the new ETAG 001 Annex E. Three design options The design code incorporates three design approaches which are described below. Note that all three of these approaches are acceptable within their application conditions. a1) Capacity design The anchorage is designed for the force corresponding to the yield of a ductile component or, if lower, the maximum force that can be transferred by the fixture or the attached element. a2) Elastic design The fastening is designed for the maximum load assuming an elastic behavior of the fastening and of the structure. b) Design with requirements on the ductility of the anchors This design for ductile steel failure requires an anchor classified as ductile. Additionally, this approach is applicable only for the tension component and some provisions require to be observed in order to ensure that the cause of failure is steel failure.

After an earthquake, fire, smoke and water damage can cause severe problems including: ■ Damage to mechanical and electrical equipment ■ Breaking/leaks in pipe systems ■ Damage to electrical lines, including emergency equipment, lighting ■ Damaged communication networks ■ Gas leaks, creating an explosion risk ■ Blocked, unusable escape routes Once these problems have been managed there will also be a need for repair, maintenance and reinspection. Hilti seismic tests Hilti has conducted extensive tests to determine the behavior of firestop products in a seismic event while taking fire integrity and smoke tightness issues in a post-earthquake environment into consideration. Test setup The quasi-static cyclic loads according to FEMA 461* protocol were applied directly on the penetrants, whereas the wall was fixed. Tests were carried out in x-direction (load in same direction as the penetrant), in y-direction (load perpendicular to the penetrant) and in z-direction (rotation with the center in the wall layer). Air/gas tightness was measured during the test with a pressure testing device to reach measurable conclusions about damages of the penetration seal. After the seismic test an additional firestop test was conducted to evaluate permeability of smoke and fire integrity of the relevant firestop system. Results Significant factors that were measured: displacement (mm), movement force, pressure drop (Pa/min), start of pressure drop (mm), % pressure drop, plastic deformation of penetrant (kN), absolute pressure at start (Pa). Determining factors: flexibility-elasticity, adhesion, tightness, damage to penetrants, installation reliability. Outcome: recommendations for suitable and non-suitable firestop products, installation and design recommendations. * Federal Emergency Management Agency: Code for interim testing protocol for determining the seismic performance characteristics of structural and non-structural components.

The French state of the art defines a seismic test method for the entire system. A design method based on EN 1998-1-1 (Eurocode 8) for non structural elements is also defined (document CSTB 3725 dated January 2013). For more information, please contact our technical back office. Test setup Three tests are defined: Required displacement ■ Parallelogram test: This test is performed to observe the behaviour of the system to follow the movement of the building on which it is fixed. The ventilated facade is installed on a rigid frame (3 000 x 3 000 mm) fixed on the bottom. The support is gradually deformed in its plane (parallelogram) by a static displacement applied at the head according to the cycles predefined. The maximum displacement is ± 60 mm. A visual control is done on fall elements, breakage or deformation of a component system. Parallelogram test Required displacement ■ Dynamic test: This test is to observe the behavior of the system when the support on which it is mounted is moving in its plane under the action a cyclic reciprocating motion imposed. The ventilated facade is installed on a rigid frame (3 000 x 3 000 mm) on gliders. Cycles of movements are applied around the frequency of the system. The maximum displacement is ± 60 mm. A visual control is done on fall elements, breakage or deformation of a component system. ■ Dynamic perpendicular test: This test is the same as the dynamci test with movement perpendilar to its plane Gliders Dynamic test Brackets Profiles Bracket MFT-MFI M For sliding point L Profile In Aluminium, thickness 2,0 mm and 2,5 mm Bracket MFT-MFI L For fixed point T Profile In Aluminium, thickness 2,0 mm and 2,5 mm www.hilti.fr/sismique 9 Installation systems need to be designed specifically to resist of seismic loads Pipes For pipes installation, the basic principle is that the fastenings have to be designed so that the horizontal seismic loads can be taken in addition to the gravity forces. To take horizontal forces, the pipe fastenings must either be designed to be sufficiently flexurally stiff, or have bracing that can transfer the horizontal forces (Fh) in compression. It must be ensured that horizontal loads can be taken transversely and longitudinally in relation to the pipe axis. Horizontal seismic forces Fh,y in direction of pipe axis Horizontal seismic forces Fh,x transverse in relation to pipe axis Standard fastening for single fastening of pipe (non seismic zones) Seismic zones: Fastening with baseplate and HST stud anchor Method of securing: 45° axial brace and transverse brace with rod and MQ3D-A. 10 www.hilti.fr/sismique Hilti solution for earthquake applications Exemples of solutions Channel installation Raised floor Standard construction of raised floors (non seismic zones) Standard fastening for channel installation (non seismic zones) Standard construction of raised floors with support framing (non seismic zones) Seismic zones: Fastening with HST stud anchor Stable U-support assembled from MQ installation channel system.
