The advantages of composite structures are: 1. Heat and electricity are not a concern for composite buildings. 2. Composite structures are lighter than conventional ones, making them simpler to carry and erect. 3. Engineers may design buildings to suit their demands since these structures are versatile. The disadvantages of composite structures are: 1. High raw material costs and usually high fabrication and assembly costs, poor strength in the out-of-plane direction where the matrix carries the primary load. 2. Composite structures are susceptible to impact damage and have greater difficulty repairing them than metallic structures.
