Some vital information about Spandrel Beams
In concrete and steel construction, spandrel beams are basically load-bearing beams which are connected with simply the support columns alongside the structure’s circumference or the circumference of the structure.
About the perspective of tall buildings, masonry walls are usually not able to bear their own weight as well as the weight of the slab.
Therefore the beam is furnished with other or different walls at every floor level to uphold or support the load on the wall as well as perhaps specific load on the roof too.
Furthermore, spandrel beams are beams constructed alongside the exterior wall of every floor of the house. Moreover, it’s a horizontal frame, formed of concrete or steel, constructed alongside the outdoor of the building to keep or bear loads of walls or some loads of roofs above it.
Also, spandrel beams are even known as edge beams. Those are offered in instances wherein the wall going to be constructed doesn’t carry the weight of the floor or the slab.
Characteristics About Spandrel Beams:
The two arrangements might or might not be under the spandrel beam. Furthermore, there might be a window or a column under a spandrel beam.
- Spandrel beam is offered alongside the external wall of the house.
- Furthermore, spandrel beams might be placed between the windowsill or the sill of the window as well as the window head or the head of the window.
- Also, spandrel beams might be extended levelly from a column to other in R.C.C. or steel systems. Those systems are going to support or uphold the wall too.
- Moreover, the parapets are put above the roofs of roof structures or frameworks.
Furthermore, the construction of beams like flanged floor beams like L-Beams as well as T-Beams is quite resistant to torsional stresses with respect to rectangular floor beams.
Therefore, edge beams or spandrel beams are constructed as flanged floor beams, which incline to enhance the total load potential of the high-rise building or structure.
Furthermore, in the arrangement of the spandrel beam, the load out of the slab is spread to the columns through the beams via torsion. Moreover, the beam even needs additional strengthening to avert torsional collapse.
Moreover, ACI Committee 318 states the prerequisites as well as instructions with respect to the construction of spandrel beam across the Building Code Requirements with respect to reinforced concrete through commentary (ACI 318-19).
Also, in flat slab structures, spandrel beams are even utilized to strengthen the link amid the two slabs and the edge columns.
Benefits of Spandrel Beam:
- The external walls of the multi-storey building are upheld or supported by spandrel beams.
- With respect to buildings having huge beam-column links, the application of a spandrel beam is recommended to enhance seismic efficiency. Those applications of spandrel beam comprise both longitudinal as well as transverse reinforcement.
- Furthermore, spandrel beams increase the lateral stability of steel as well as concrete.
- Moreover, spandrel beam is utilized together with coupled shear walls to increase stiffness as well as ductility in opposition to earthquake activity.
- Also, spandrel beams offer protection for external side openings like shear walls windows as well as lintels.
- Moreover, spandrel beams have additional support on the external walls of a multi-floor structure.
- Furthermore, spandrel beams for both transverse as well as longitudinal reinforcement, which enhance the seismic performance of the structure, are preferred for huge beam-column ties.
Demerits of Spandrel Beam:
- As spandrel beams are placed on the exterior of a structure, they’re usually quite susceptible or vulnerable to moisture as compared to floor beams leading to the worsening or deterioration of reinforcing steels.
- Because of cracking as well as chewing asphalt, considerable money is disbursed on reconstruction.
