On the Thin-Walled Theory’s Application to Calculate the Semi-enclosed Core Structure of High-Rise Buildings

  • 1771 Accesses

Part of the Lecture Notes in Mechanical Engineering book series (LNME)


The shape of a high-rise building’s core structure is usually semi-enclosed; the coupling beams connecting the two boundary walls at the floors’ level play an essential role in the core’s working.

The discrete-continuous model used to calculate semi-enclosed core structures based on the thin-walled theory proved useful and evaluated the overall working and structural components’ behavior in the core. However, this theory also has certain assumptions about the correlation between core boundary walls and coupling beams.

The paper will investigate cases of core’s boundary walls corresponding to the several instances of the height of coupling beams according to the thin-walled theory and compare the results with those of the SAP2000 structural analysis program to evaluate and figure out the correct use of the calculation theory. The research results serve as a basis for the design of the core structures of high-rise buildings.
