A high-rise structure is a tall building typically defined as one with more than 10 to 15 stories, although the exact threshold may vary by region. These buildings are designed to accommodate large numbers of people or businesses and often feature advanced engineering techniques to handle wind, seismic activity, and other environmental factors. High-rise structures often incorporate materials like steel, concrete, and glass, and are equipped with specialized systems for fire safety, elevators, and air conditioning. They are commonly found in urban centers and are key components of modern city skylines.
