Structural engineering companies can be found in this category. Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to understand, predict, and calculate the stability, strength and rigidity of built structures for buildings and non building structures, to develop designs and integrate their design with that of other designers, and to supervise the construction of projects on site. They can also be involved in the design of machinery, medical equipment, and vehicles where structural integrity affects functioning and safety.
Structural engineers often work alongside civil engineers and architects as part of a construction team. Structures must be able to deal with the conditions in which they are built. When building bridges, designers must take into account the conditions of terrain, wind, water and traffic volume. Structural engineers consider all of these factors and provide technical advice about the project.
They are experts at solving problems, meeting challenges and providing creative solutions.
Structural engineers design roof framing; beams, rafters, joists, trusses, floor framing floor decks, joists, beams, trusses, girders, arches, columns, braces, frames, foundations and walls. In bridges, they design the deck — or riding surface, girders or stringers, and piers. The materials they use include steel, concrete, wood, masonry, and aluminium. Engineers design the structure to resist forces from gravity, earthquakes, high winds, water, soil, collisions and blast explosions."
Critical skills that a person needs in structural engineering include an in-depth understanding of physics and mathematics. A structural engineer must also know the properties of various materials, such as their density, hardness, tensile strength, bulk modulus and bending strength. They need to be able to calculate how different materials will perform under stresses such as compression, tension, bending and twisting, as well as under various environmental conditions of temperature, pressure, corrosive gases and liquids, and even radiation. They also need to be able to predict how these materials will perform over an extended period of time.
A structural engineering firm provides the engineers that work together with a construction team of architects, civil engineers and building contractors. These Zambian companies are listed in this category.
