There have been numerous reports detailing the cause of the World Trade Center Tower collapse on September 11, 2001. Most have provided qualitative explanations; however, simple quantitative analyses show that some common conclusions are incorrect; for example, the steel could not melt in these flames and there was more structural damage than merely softening of the steel at elevated temperatures. Some guidelines for improvements in future structures are presented. 

The World Trade Center disaster : Analysis and recommendations

The terrorist attacks of September 11, 2001 brought about the destruction of two symbols of American economic strength, the twin towers of the World Trade Center in New York City. These towers

Fourteen Points of Agreement with Official Government Reports on the World Trade Center Destruction

Reports by FEMA and NIST lay out the official account of the destruction of the World Trade Center on 9/11/2001. In this Letter, we wish to set a foundation for productive discussion and

Why Indeed Did the WTC Buildings Completely Collapse

In this paper, I call for a serious investigation of the hypothesis that WTC 7 and the Twin Towers were brought down, not just by impact damage and fires, but through the use of pre-positioned

Materials and structures

The collapse of the World-Trade Center towers, on September 11, 2001, has raised questions about the design principles in high-rise buildings. In this article, we first consider the likely failure

Extremely high temperatures during the World Trade Center destruction

In an effort to better understand the conditions that led to complete collapses of the World Trade Center Towers and WTC 7, we apply scanning-electron-microscope (SEM) and energy dispersive x-ray

Energy balance in the WTC collapse

The main aim of this report is to provide an analysis of Twin Towers of the New York City’s World Trade Centre collapsed after attacked by two jet aircrafts. The approach mainly focused on the effect

Why Indeed Did the WTC Buildings Collapse

We start with the fact that large quantities of molten metal were observed in basement areas under rubble piles of all three buildings: the Twin Towers and WTC7. A video clip provides eye-witness

Destruction of the World Trade Center North Tower and Fundamental Physics

The roof line of the North Tower of the World Trade Center is shown to have been in constant downward acceleration until it disappeared. A downward acceleration of the falling upper block implies a

How fast does a building fall?

In this paper, the time required for a tower block to collapse is calculated. The tower collapses progressively, with one floor falling onto the floor below, causing it to fall. The rate of collapse
