Collapse analyses of the World Trade Center towers following 9/11 by SGH

Collapse analyses of the World Trade Center towers following 9/11 by SGH

This is the last two-thirds of a presentation by Simpson Gumpertz & Heger given on January 26, 2024. There was a Q&A at the end and I can tell you from attending the webinar that the questions were cherrypicked for the softball questions. This is an example of how the narrative is controlled. FROM THEIR SITE: The collapse of the World Trade Center (WTC) towers in New York City on 11 September 2001 was an unprecedented event in U.S. history. Following the terrorist attack, the National Institute of Standards and Technology (NIST) conducted an extensive investigation of the collapse. They retained Simpson Gumpertz & Heger (SGH) and Applied Research Associates (ARA) to develop computer simulations of the structural response of WTC-1 and WTC-2 to aircraft impact and subsequent fires, and of WTC-7 to damage from falling debris from the WTC-1 failure and the resulting fires. The study found that the tower collapses were caused by the combined effects of aircraft impact damage to the structure and its fireproofing, and the subsequent fires. In this hybrid webinar event, we will hear from the principal investigator of this collapse initiation analysis. Through a series of pre-recorded videos and animations, as well as live questions and answers, SGH’s Mehdi Zarghamee will describe the WTC collapse, discuss the NIST study and approach, and share the results of these efforts. This project posed enormous challenges that stretched the limits of computational modeling and analytics at the time. The project team had to invent new analytical methodologies that extended the existing computer program’s capabilities to meet the analysis of progressive failures of structures leading to total collapse. In the end, this work advanced the state of the art in the industry and formed the basis of a new act by Congress, as well as revisions to many codes and standards that govern the design of tall buildings in the United States and abroad. https://www.sgh.com/news-event/01-26-24-webinar-collapse-analyses-world-trade-center-towers/ ABOUT THE SPEAKER Mehdi Zarghamee | Senior Principal 781.907.9203 mszarghamee@sgh.com Mehdi Zarghamee has a dedicated career with extensive consulting, academic, and management experience. He specializes in structural engineering and applied mechanics, infrastructures, and mathematics, with experience involving analysis and design of complex structures and mechanical systems; structural investigations, including condition assessment and failure risk analysis; and repair, rehabilitation, and asset management of deteriorated infrastructures.

Engineer Tony Szamboti: Official theory of Twin Towers’ destruction built on glaring errors - 4K

Today we proudly release a powerful extended interview with mechanical engineer Tony Szamboti, who appears in The Unspeakable as a friend of 9/11 family member Bob McIlvaine. In this interview, Szamboti summarizes the glaring errors in the analysis by engineering professor Zdeněk Bažant, who, in a series of papers published between 2002 and 2011, purported to explain how the Twin Towers could undergo total collapse once the tops of the towers began to fall. Bažant’s theory was relied upon by NIST — the federal agency tasked with investigating the World Trade Center failures — which remarkably neglected to conduct any analysis of the towers’ behavior after the point of “collapse initiation.” https://www.ae911truth.org/news/857-oh-the-irony-as-editor-of-the-journal-of-engineering-mechanics-zdenek-bazant-wrote-a-letter-encouraging-discussions Szamboti also shares how his critique of Bažant’s latest paper in 2011 was astoundingly rejected as “out of scope” by the journal that had published the paper — a decision he is fighting to this day. The Unspeakable One lost his son, another his mother, another his brother, another his best friend. Twenty years later, these four men and their families live with the knowledge that they were not told the truth about the murder of their loved ones on September 11, 2001. In the face of overwhelming resistance, they continue to fight for the justice they deserve.

Former Prosecutor & Structural Engineer Examine Surfside Bldg Collapse - The New WTC Bldg 7?

Former Prosecutor & Structural Engineer Examine Surfside Bldg Collapse - The New WTC Bldg 7?

Former prosecutor and host of The Professor's Record David Clements joins me with his wife, Erin, to talk about the recent building in Surfside, Florida that is being attributed to some type of structural failure, but was actually nothing like that at all. In fact, we can draw parallels to the World Trade Center on 9/11, specifically Building 7. They not only provide structural analysis, but also ask important questions on who would be behind the destruction of the building and why. Professor Clements teaches law at New Mexico State University, and was a long time prosecutor that oversaw 6 law enforcement agencies, and tried many high profile cases, including first degree murder. He came to national prominence after appearing on Tucker Carlson after standing up to his university's targeting of conservatives. He is also a contributor to Bannon's War Room on election integrity issues. His wife Erin is a registered professional engineer with 17 years experience in structural and civil engineering, holding degrees in both disciplines. She has experience in inspection of existing structures and in recommending and designing repair and replacement projects as well as design of new structures.

Subsea Pipeline Failures & Corrosion Online Course

Subsea Pipeline Failures & Corrosion Online Course

Pipelines are an essential part of the oil and gas industry as they are the main means of transportation. As the offshore technology advances, subsea pipelines are being operated in more demanding environments. For the pipelines to operate efficiently, they have to be carefully designed. One of the main threats to the integrity of the pipeline is corrosion, which has caused many failures. Corrosion in subsea pipelines has different forms and understanding their mechanisms is an important step in inhibiting them and decreasing their rate of occurrence. As corrosion is unavoidable, it is beneficial to be able to calculate the corrosion rate and the corrosion allowance. By obtaining the results of the corrosion rate it becomes clearer which type of group of steel to consider for the fabrication of the pipeline. Subsea engineers battle harsh, corroding marine environments, as well as corrosive fluids that flow inside the pipeline, leaving pipelines extremely susceptible to damage. There are also many variables to consider when dissecting pipeline systems, such as differing installation processes, diameter and thickness of a pipeline, aging in hardware and materials failure. For instance, rigid pipelines are often made of carbon steel and are stiff and hard to install. In contrast, flexible pipelines are relatively easier and cheaper to install but difficult to maintain.
