Press Release Overview
The press release, issued on 28 July 2026, announces that Unternehmensgruppe fischer, in partnership with Purdue University (USA), has successfully completed full‑scale seismic retrofitting tests on reinforced‑concrete structures. The research focused on beam‑column joints, which experience the highest stresses during horizontal earthquake loading.
Test Methodology and Technical Solution
A novel retrofit system comprising bonded anchors, haunch elements, fischer injection mortar, and threaded rods was applied to full‑scale beam‑column joints. According to Dr Margaritis Tonidis, former PhD candidate at Purdue and project engineer, the bonded‑anchor system exhibits negligible deformation under load and reliably transfers forces, allowing the haunch retrofit to protect the joint during seismic stress. The system alters the force flow, redistributing loads to adjacent structural members and defining failure mechanisms that prevent total collapse.
Performance Results
Prof Akanshu Sharma, Associate Professor at Purdue University and former Endowed Professor at the Institute of Materials Science, University of Stuttgart, described the injection mortar as a highly reliable adhesive anchor that performed exceptionally under high seismic demands, delivering groundbreaking results. Comparative testing showed that the unstrengthened control structure suffered major damage to its beam‑column joints, whereas the structure strengthened with the fischer system demonstrated superior performance, maintaining load‑bearing capacity and exhibiting high rigidity with low deformation at high‑load levels. Prof Sharma also noted that the retrofit can be installed while the building remains occupied, avoiding major interruptions.
Expert Commentary
Dr Erik Johannes Stehle, Head of Development FiXperience at fischer, emphasized that the success of any seismic reinforcement solution hinges on anchorage performance, and the bonded‑anchor system achieved impressive structural‑level results. Both Dr Stehle and Prof Sharma highlighted the importance of international research collaboration, stating that joint efforts between the scientific community and industry drive innovation and reinforce fischer’s position as a global innovator.
Significance for India
Mayank Kalra, Managing Director of fischer India, stated that India is among the fastest‑growing infrastructure markets and possesses several regions vulnerable to seismic activity. While modern construction adheres to advanced earthquake‑resistant standards, strengthening existing pre‑code buildings remains equally critical. The validated retrofit solution offers a realistic, affordable means to enhance structural safety, extend the service life of existing infrastructure, and contribute to more resilient cities. Kalra affirmed fischer India’s commitment to bringing globally proven engineering solutions to the Indian market.
Contextual Background
The release notes that approximately 500,000 earthquakes are recorded worldwide each year, with heightened risk in the Pacific Ring of Fire, the Himalayas, the Mediterranean, Central America, and the Caribbean. Human activities such as oil and gas extraction, fracking, geothermal drilling, and large‑reservoir construction can also trigger seismic events. Existing buildings constructed before modern earthquake standards are particularly vulnerable, underscoring the urgency of retrofitting solutions.
