• Construction stages analysis is as important as the analysis for the permanent structure. • If the limitation for the crack width is exceeded within three weeks, this a good sign of a brittle failure. • Ductility is a key property for a good structural system. Every civil engineer need to read this report.
Lessons learned from the 2018 Florida bridge collapse during construction This was a bridge of an unusual design and was being constructed in an unusual manner. The main 53m pre-stressed pre-cast concrete span truss was in position when cracks appeared at a node and over a period of almost three weeks they visibly worsened until collapse occurred.

🌉 This article explores the design and construction of concrete arches, frames, tunnels, and jacked box bridges, referencing methods from the Concrete Bridge Development Group (CBDG) guidelines. Key insights include load management, material durability, and advanced erection techniques like balanced cantilevering and rotational methods of concrete bridge construction. 👉 Read the full article here: [https://lnkd.in/dx9Jmbcs] #ConcreteBridges #BridgeDesign #StructuralEngineering #InfrastructureEssentials

The high-corrosion and rust- resistance features of TMT Bars make it the first choice for buildings in coastal areas and in areas of high humidity. Its ductility and bend ability makes it the perfect choice for buildings in seismic zones for high-stress construction structures. #TMTBars #BuildingResilience #CoastalConstruction #SeismicSafety #InfrastructureInnovation #RustResistance #GlobalTradeLinks #GTL

The author of this document identifies a number of concerns that ring very true about decision making and lack of qualified supervision on construction sites. Sadly the role of the Resident Engineer is long gone, and all too often design information is indeed provided to Contractors who never refer to the Engineers again. Fundamentally this bridge is unusually designed: the Architectural concept being a cable-stayed bridge which would have slender light weight deck construction; being translated into a concrete truss with a tower and steel tubes for decoration purpose only was an immediate recipe for disaster. No doubt the decision to change from the Architect concept was driven by cost and a belief that by precasting a truss it could be installed in a single operation (probably with an overnight road closure). From that moment on the Engineer would have been under constant pressure to reduce member sizes to maintain the slender appearance of the bridge. However, the decision to post tension the diagonal strut, which is clearly a compression member that was cracked and undergoing compressive failure was in my option a decision of criminal incompetence. It is easy to see what went wrong in hindsight, but so often difficult to be the one who makes a stand against the wave of Parties who all think they know best and sadly only those directly involved will have learned the lessons. Well worth 10-mins to read!

As plans to tackle the UK housing crisis keep making headlines, Rt Hon Rachel Reeves has outlined plans to implement quicker and more efficient construction techniques. The necessary solutions already exist with modern methods of construction. ICF Bondmor is continuing to develop and implement these solutions to help achieve the targets and build a better, stronger, and more sustainable future. Working with #SmallerHousingAssociations and #UKHousing developers we can provide a "Fabric First" approach to operational energy efficiency, reducing carbon emissions and reducing operational costs.

Have you ever considered ICF but then decided to go with the build system you already know? Maybe it’s time to choose an alternative option. One advantage (amongst many) of building with an insulated solid wall construction method like ICF is that the blocks are lightweight and stackable. This makes them much easier to transport to site with fewer delivered needed and a reduced requirement for lorries. Ideal for difficult to access sites. #ConstructionSimplicity #ICF #InsulatedSolidWallConstruction #ICFA https://lnkd.in/d4Xj96Tk
