Unlike the Twin Towers, WTC 7 was not directly hit by an airplane, yet it collapsed completely, making it the first known instance of a tall building brought down primarily by uncontrolled fires. This article aims to explore the structural causes behind the collapse of WTC 7 from an engineering perspective.

The vapor cloud found an ignition source - most likely a running vehicle or a spark from a nearby contractor's trailer - and ignited. The resulting explosion was equivalent to approximately 1,000 to 2,000 kilograms of TNT, and it was felt up to five miles away.

On November 18, 1999, the traditional Aggie Bonfire, an iconic annual event at Texas A&M University, suffered a devastating structural failure that led to the death of twelve people, while injuring twenty-seven. The Aggie Bonfire was more than a mere bonfire; it was a towering structure of log stacks reaching nearly sixty feet high, an emblem of Aggie spirit and camaraderie. The collapse, which occurred during construction, was a shocking tragedy that deeply affected the University and the broader community.

The Denver International Airport (DIA) is renowned for its iconic tent-like structure, but it is also infamous in engineering and project management circles for its ambitious yet flawed automated baggage-handling system. This system, which was intended to revolutionize the airport industry, instead became a case study in the pitfalls of over-ambitious engineering and poor project management.

The Westwego explosion was one of the deadliest grain-dust explosions in history, and it had a profound impact on the industry and the community. In the aftermath of the disaster, investigators worked tirelessly to determine the cause of the explosion and to prevent similar tragedies from occurring in the future.

The Tropicana Casino Resort was one of Atlantic City’s premier gambling destinations, drawing thousands of visitors each year. As part of a major renovation effort, the Tropicana embarked on an ambitious construction project to build a nine-story parking garage.
