About this event

This webinar is part of the “Seismic Retrofit Strategies for Existing Structures” series, designed to equip structural engineers with region-specific guidance on retrofit challenges and anchorage design, jointly hosted by ClearCalcs and PYTHON Fasteners. 

In this Australia-specific session, join PYTHON Fasteners Engineering and Sales Manager, Kieran Bisacre-Peters, on Thursday, September 25, 2025, from 12 pm to 1 pm (AEST) to take a deep dive into anchoring services and seismic bracing to hollowcore floor systems—a critical area of design where safety, capacity, and constructibility intersect. You’ll gain clarity on how to interpret C1 and C2 capacities, understand key limitations in anchoring to precast concrete, and walk away with practical design strategies for achieving compliance and performance in real-world retrofits.

Whether you’re reviewing seismic bracing plans, designing service fixings, or overseeing retrofit anchor specs, this session is for you.

All registered attendees will receive a recording of the webinar after the event.

In this webinar, we will cover:

• Anchorage techniques for hollowcore floors: capabilities, constraints, and trade-offs
• Understanding and applying C1 & C2 capacities in Australian design contexts
• Common pitfalls in anchoring to precast floors for seismic or service loads
• Design recommendations to improve constructibility and maximise retrofit efficiency

We’ll explore field-tested insights to help engineers make better-informed decisions when designing for hollowcore anchorage—especially in retrofit or post-installed applications.
