Famous building failures teach us important lessons about how things work in physics. They help us understand what makes structures stay strong and why safety is so important when designing and building. Each failure shows us what can go wrong and what we can learn to improve.

One well-known failure is the Tacoma Narrows Bridge, which fell down in 1940. This bridge, nicknamed "Galloping Gertie," collapsed because of strong winds. It reminds us to think about the forces from nature when making designs. Here’s what we can learn:

• Dynamic Loading: Buildings must be built to handle not just normal weights, but also changing forces, like strong winds.
• Aerodynamic Design: The shape of a building should consider how air moves around it, which can help lessen the impact from winds.

Another example is the John Hancock Center in Chicago. Built in 1969, this building faced strong winds but didn’t fail because it used a smart design with a braced core system. From this experience, we learn:

• Bracing Systems: Good bracing helps tall buildings stay steady in windy weather.
• Safety in Design: Using safety measures in the design process helps prepare for unexpected situations.

The Hyatt Regency walkway collapse in 1981 is a sad example of what can happen when designs aren’t properly checked. This disaster happened because of flaws in the design that weren’t properly reviewed. Key lessons are:

• Design Review Processes: It’s important to have careful checks in place to make sure any changes to designs are safe.
• Load Path Understanding: We need to know how loads move through a building so that everything is supported properly.

The Sampoong Department Store in South Korea fell down in 1995 due to bad materials and construction. This tragedy teaches us:

• Material Quality: Using materials that meet safety standards is very important for strong buildings.
• Construction Practices: Sticking to good construction methods and following safety rules can prevent avoidable disasters.

The Ponte Morandi bridge in Italy also collapsed in 2018 due to neglect and lack of maintenance. This sad event shows us the importance of:

• Regular Inspections: Keeping up with maintenance and checking structures often can help catch problems before they turn serious.
• Aging Infrastructure: Buildings age over time, and we need to understand how this affects their safety.

We can also learn from the Ronan Point apartment building in London. It had a partial collapse after a gas explosion in 1968. This incident highlighted:

• Robustness
