What Types Of Structures Can Be Designed Using Structural Engineering Principles?

 1,174 total views

Structural engineering is a subfield of civil engineering that focuses on the framework of buildings and on constructing them to withstand environmental loads and pressures while keeping them safe, stable, and secure throughout their usage. Engineers who specialize in structural designs guarantee that structures like buildings and bridges don’t collapse.

Structural engineering is one of the earliest subfields of engineering. Humanity has been creating more complicated and vital structures throughout history, ranging from modest huts to global space stations.

What Do Structural Engineers Do?

To ensure that the simple structures we use, like bridges and tall buildings, are safe and stable and do not collapse under applied stress, qualified professionals offer structural engineering services. Structural engineers employ their technical know-how to specify a wide range of building material types in various shapes and geometries. They then create structures that can withstand the stresses and pressures of their environment, such as dynamic loading, storms, and earthquakes. Depending on the function of the building, specifications and construction requirements can be utilized to determine the weight of the building as well as snow, weather, and seismic loads on the structures.

Various Types Of Structures Designed By Structural Engineering

Structural engineering concepts are widely used to create different kinds of structures:

  • Structure For Bearing Load

The roof and floors of the structure, which are directly supported by a load-wearing framework, carry the weight of the structure to the walls. Wall toeholds that support 2 to 4 stories effectively and economically distribute the weight of the walls on the ground below. Due to its load-bearing feature, the wall width decreases floor space as the number of stories increases. This type of structure is used where shallow depths of stiff strata are accessible and the wall toeholds are instantly set on their levels. Only transitory or modest structures are employed as load-bearing structures today.

  • Structure With Frames

Structures called frames are composed of transverse and longitudinal components. The horizontal elements are called beams, while the vertical components are called columns. By bending beams and columns, a rigid frame can withstand both vertical and lateral loads. A pin or fixed connector connects a beam with a column to form a frame. Except for rigid joint connections, fixtures can be stretched into three or two dimensions. There are two categories of frames: swaying and non-swaying. Non-swaying frames are rigid in nature while a sway frame permits sideways or lateral gestures but not a horizontal element.

  • Shell Structure

A narrow, curved plate structure called the shell transmits applied forces through tensile, compressive, and shear stresses that act in the surface plane. The materials used to build the structure have a minimal deepness compared to other dimensions; the external surface can be a tent or a puffed structure. In both cases, the surface equipment and material function as an integument only subjected to pure stress. It may also be constructed from concrete and shaped like a cylinder, a replicate plate, or another object. This structure can sustain loads in tension and compression with a small degree of bending.

  • Composite Structure

A load-bearing structure and a frame structure make up a composite structure. External walls may sustain loads, while internal column and beam structures may sustain floors and ceilings. These structures are frequently employed as industrial sheds or storage facilities with extraordinarily long spans.

Selecting Appropriate Materials

One of the essential duties of structural engineers is choosing suitable building materials for providing high-quality BIM modeling services. The materials used to build a structure determine the building’s capacity to endure internal and external forces, maintain equilibrium, and remain stable. Structural engineers use several parameters for the material selections such as:

  • How far a material can be stretched before losing its shape is measured by its elastic properties.
  • The ability of a material to distort in a plastic manner is measured by plasticity. Plastic deformation happens when a material is stretched past the point at which it can no longer regain its original shape. Metals are more complicated to work with than other materials that break, like glass, because they flex plastically.
  • Strength measures a material’s capacity to withstand applied stress or load without failure.
  • Toughness is measured by how much power will cause a given material to fracture.
  • Brittleness refers to a material’s tendency to fracture under stress but to only slightly deform before rupturing.

Conclusion

In contrast to immense, expensive, or unusual structures that are difficult to verify, most ordinary structures are planned by a competent professional engineer using complex computations. They design and evaluate dams, power plants, electric towers, bridges, monumental buildings, and other critical infrastructure.

The primary duties of structural engineering involve connecting numerical representations of physical forces to actual arrangements of force-resisting components. Along with other engineers, structural engineers have a big responsibility to make sure that the general public is safe and protected.
