Building Interruption Joint Calculation | New 2025 Standards and Implementation Solutions
Why is calculating seismic joints critical? In civil engineering, calculating building seismic joints is one of the key elements for ensuring the safety of structures against earthquakes, thermal expansion, contraction, and soil settlement. This small gap between two adjacent buildings prevents them from colliding during seismic movements and can save lives and property. According to […]
History of the Discontinuity Seam | Evolution, Rules, and Its Impact on Building Safety
In the world of modern architecture and civil engineering, seismic joint covers act as one of the key elements in increasing the safety and durability of structures. These covers not only absorb movements caused by thermal expansion, soil settlement, and seismic vibrations but also prevent the penetration of moisture, dust, and environmental factors, preserving the […]
Gap Sealing in Buildings | Why is gap spacing critical?
Iran is one of the countries with high earthquake risk in the world. Buildings constructed without observing seismic reinforcement principles are vulnerable to moderate and severe earthquakes. One of the key factors in earthquake-resistant building design is the seismic joint and the implementation of seismic joint covers. A seismic joint cover refers to the distance […]
