Fluor Corporation’s Post

Bracing systems are components of steel structures, they play a crucial role in stability and safety of modern buildings. They resist lateral forces like wind, seismic, and other loads that can cause the building to sway or collapse. A well-designed bracing construction can improve a building’s ability to withstand these forces and minimize damage to the structure . Some of the most common ones include V-bracing, inverted V-bracing, diagonal bracing, X-bracing, and K-bracing.

• 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.

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!

This is a report that very engineer needs to read, whether they design bridges or not. #structuralengineering #civilengineering #constructionsafety #bridgeengineering

Another beautiful little 13 ton compactor plate collected by a returning customer today. Once people try our attachments and really understand the high quality that is built into them, they always come back for more. Our high quality equipment is also amazing value for money, and on top of that, it is all backed up by our very own service & support that we have been known for, for over 40 years in the business.. we love what we do, and we do it well..! If you would like to talk to us about rock breakers, compactors, selector grabs, land rakes, augers, or rippers just give us a call and let us show you what we are about.

Thanks Frank for your great presentation this morning! One takeaway for me was that of mortarless masonry. The precision required for the stonework to stay together was eye opening to say the least. Contact Frank at Fort Erin Construction to learn more about mortarless stonework or any other masonry questions you may have.

Segments from the Past! A look into our construction archive finds winter construction photos of the new I-76 Allegheny River Bridge in Oakmont, Pennsylvania. Daily winter temperatures in nearby Pittsburgh averaged 20oF during the construction of this project. Balanced cantilever construction began from pier tables cast in place atop twin wall piers to provide a platform for launching the traveling forms. One side of the pier table was 16’ long while the other side was 24’ long. The asymmetry kept the cantilever balanced within a half segment, minimizing out-of-balance loads on the piers. Constant 16’ long segment lengths were used for ease of construction. Year-round cantilever construction utilized four traveling forms for the superstructure to meet the project schedule. The I-76 Allegheny River Bridge is the first cast-in-place concrete segmental bridge in Pennsylvania and features a 532’ main span across the Allegheny River. FIGG designed this bridge for the Pennsylvania Turnpike Commission and provided construction engineering and inspection support to the Owner. #civilengineering #transportation #bridge #SegmentsFromThePast

In a world facing climate extremes and increasing environmental responsibility, the demand for resilient building solutions is at an all-time high. Concrete masonry construction stands out as a key player in meeting these challenges. Known for its robust structural integrity, safety, and resilience, concrete masonry also offers significant yet often overlooked advantages such as aesthetic appeal, design versatility, energy efficiency, and low embodied carbon. CMUs are an essential choice for future-proofing our communities against the evolving demands of our environment. #CMU #ConcreteMasonry #ConcreteMasonryCheckOff #SustainableArchitecture #CMUCheckoff
