Remediation and Retrofit of Existing Masonry Structures: New Zealand Approaches

Discover practical retrofit strategies for unreinforced masonry (URM) buildings in New Zealand, backed by field data from the Christchurch earthquakes and global research collaborations. In this ClearCalcs Learning Hour, Robert from PYTHON Fixings shares proven solutions for parapets, chimneys, wall-to-diaphragm connections, cavity walls, and diaphragms—along with the anchor systems that perform best in seismic events. You’ll learn: • How steel bracing, post-installed rebar, and post-tensioning compare for parapet safety. • Why epoxy anchors often fail in historic masonry and when mechanical anchors are a better choice. • Practical use cases for timber strongbacks, CLT panels, and plywood shear walls. • Cost-effective ways to increase out-of-plane wall capacity using composite action and post-tensioning. • Inspection tips for cavity wall ties and guidance on choosing the right retrofit method for your project. This session is ideal for structural engineers, heritage consultants, and building designers working in seismic regions who want code-aligned, field-tested retrofit strategies.
