“**It's extraordinarily rare for a building like that to collapse, especially in the U.S.**,” Fred Bloetscher, a professor of civil engineering at Florida Atlantic University, told The Post Saturday. “We have extensive building codes used by engineers with built-in factors of safety.

A building can collapse while it is being erected or demolished, **as a result of a neighboring demolition, or because of a natural catastrophe such as an earthquake**. Design or construction flaws – a faulty foundation is perhaps the most dangerous type of design flaw.

**Avoid Major Alterations**

Another major cause of building collapse are the major alternations that are made to the basic exterior and interior arrangement of the structure. For example, removal of one of the beams that provide support to the building could make it susceptible to damage.

To withstand collapse, buildings must **redistribute forces that travel through them during a seismic event**. Shear walls, cross braces, diaphragms and moment-resisting frames are central to reinforcing a building. Shear walls are a useful building technology that can help transfer earthquake forces.

A building can suddenly collapse for many different reasons: faulty construction; termite damage; rot; damage caused by the weight of snow, ice, or rain over time; the weight of people or personal property; blasts; vibrations; or decay.

**The signs include:**

- Cracked or crumbling concrete. Decades ago, builders often mixed concrete at project sites, Ashraf said.
- Interior cracks.
- Uneven or bowing walls or floors.
- Diagonal cracks at the corners of windows and doors.
- Wall rotation.

**The following is a list of common signs that a floor is structurally unsafe.**

- Bulging Walls. Leaning or bulging walls are a common sign that a property may have a structural issue.
- Excessive Weight on a Floor.
- Damaged or Rotten Wood.
- Uneven Floors.
- Building a Structure with Cheap Materials.

The 18-story building is located in Miami Beach, immediately south of the Champlain Towers site in Surfside. "As numerous media reports have documented, Champlain Towers South was **improperly designed, poorly constructed, significantly underfunded and inadequately maintained and repaired**," said attorney David B.

Experts are predicting that **there could be at least one mile-high skyscraper by 2050**. There's also likely to be a trend of buildings over 3,200 feet high.

There are, in general, three approaches to designing structures to reduce their susceptibility to disproportionate collapse: **redundancy or alternate load paths** (where the structure is designed such that if any one component fails, alternate paths are available for the load that was in that component and a general

Experts say **all tall structures are bound to sway a little bit in the wind**. But builders have to be sure that super-strong winds don't topple a skyscraper. So the concrete that's used to make these tall buildings is strengthened with steel rods and beams. This steel makes up the “skeleton” of the skyscraper.

A quadratic equation is a second-order polynomial equation in one variable that **occurs in many areas of engineering**. For example, the height of a ball thrown in the air can be represented by a quadratic equation.

There are three basic methods for solving quadratic equations: **factoring, using the quadratic formula, and completing the square**.

Quadratic equations are sometimes used to model situations and relationships in business, science and medicine. A common use in business is **to maximize profit**, that is, the difference between the total revenue (money taken in) and the production costs (money spent).

Quadratic equations lend themselves to **modeling situations that happen in real life and in decision making**, such as the rise and fall of profits from selling goods, the decrease and increase in the amount of time it takes to run a mile based on your age, and so on.

In other words, **if you have a times the square of the expression following b plus b times that same expression not squared plus c equal to 0**, you have an equation that is quadratic in form. If we substitute what is in the ( ) with a variable like t, then the original equation will become a quadratic equation.

**Careers That Use Quadratic Equations**

- Military and Law Enforcement. Quadratic equations are often used to describe the motion of objects that fly through the air.
- Engineering. Engineers of all sorts use these equations.
- Science.
- Management and Clerical Work.
- Agriculture.

So why are quadratic functions important? **Quadratic functions hold a unique position in the school curriculum**. They are functions whose values can be easily calculated from input values, so they are a slight advance on linear functions and provide a significant move away from attachment to straight lines.

A quadratic function is a reasonable model for revenue because **revenue = price · quantity**. The price will be a function of the number of boxes of candy sold (this is the law of supply and demand) and thus revenue is the product of two functions of x.
