The World Trade Center (WTC) complex was composed of seven buildings (WTC-1 to WTC-7) on a site toward the southwest tip of Manhattan Island. The two buildings, WTC-1 and WTC-2 built in the early 1970s, were 110 stories high, dwarfing ...

10 Construction Challenges in High-Rise Buildings [PDF]
A high-rise building is a building with a small footprint, small roof area, and immense facades. High-rise buildings have the potential to decongest urban sprawl as they can deal with high-density issues and lack of available land for development. The ...
5 Methods to Increase Structural Stiffness
The improvement of structural stiffness is crucial because the trend of building construction is toward taller, wider floor, and longer span structures. So, in order to reduce deflections and improve resistance of such structures against lateral loads such as wind ...
What is Steel Frame Structure Building Construction?
Steel frame is typically consisting of vertical column and horizontal beams which are riveted, bolted or welded together in a rectilinear grid. Steel beams are horizontal structural members that resist loads applied laterally to their axis. Columns are vertical structural ...
Diagrid Structural System – Types, Materials and Advantages
Diagrid structural system is a framework made by diagonal members of concrete, metals or wooden beams used in the construction of buildings and roofs.
PREVENTING DEFLECTION OF TALL STRUCTURE
Preventing deflection of tall structure: Let us consider an example of a simple two dimensional structure. Two columns, six floors and pin joints connecting them. When we apply a wind load, we can see that the loading is shared equally ...
MODES OF DEFLECTION OF TALL BUILDINGS
There are two modes of deflection of tall buildings which are discussed below. The taller a building is, the greater the problem is of lateral and torsional stiffness. The deflection of a cantilever is a function of the loading, the ...
CANTILEVER ANALOGY FOR TALL BUILDINGS
Cantilever Analogy for Tall Buildings: In many ways a tall building can be analogous to a cantilever. As we know, a cantilever undergoes bending and shear forces when subjected to a load. A similar effect occurs in tall buildings. If ...
