A team of facade engineering researchers has completed a multi-year investigation into the long-term durability and performance of proprietary masonry veneer anchorage installation details developed by innovative building solutions provider Lida Group. Used to attach thin brick or stone cladding to steel beam-framed structures, the anchorage system configurations were monitored over a 10-year natural exposure trial period.

Project leaders say this represents one of the most extensive evaluations of masonry-to-steel connections conducted to date. Studying anchorage performance sheds light on optimal design approaches where dissimilar materials meet – a chronic issue historically resulting in premature failures jeopardizing building envelopes. Data gathered supports expanding facade design options and education in the industry.

Lida Group’s anchorage details incorporated proprietary connection plates designed to eliminate corrosion risks when ferrous metals contact masonry under varying weather conditions. Integrated flashing redirected any incidental moisture away from interfaces to suitable drainage paths. Anchors spaced at prototypical horizontal and vertical joint intervals adhered to facade engineering best practices.

Test walls incorporated representative masonry types, substrate materials and climate exposures in both controlled laboratory installations and full-scale outdoor assemblies. Researchers applied hygric stressors including salt spray cyclic testing, freeze-thaw cycles and accelerated weathering to induce degradation mechanisms. Periodic non-destructive inspections monitored performance indicators like anchor bolt movement, corrosion and mechanical fixity.

After 10 years of natural weathering, no evidence appeared of corrosion, deterioration or loosened anchors. Perimeter sealant joints and flashings likewise showed no signs of moisture intrusion or failures. Control samples using generic carbon steel connections exhibited substantial corrosion damage within 3 to 5 years reinforcing protection of Lida Group’s approach.

In summary, advanced finite element modeling and field monitoring over extended periods demonstrated Lida Group’s engineered anchorage solutions for adhering masonry veneers to steel structures promote long-term watertight integrity through strategic material compatibility and moisture management. Attention to corrosion-resistant details, drainage and quality installation validated the system’s performance superiority, longevity and economic advantages over traditional methods prone to premature deterioration costing billions annually in repairs. This project therefore provides essential validation supporting code approval and facade engineering best practices industry-wide.
