Investigation of Construction Vertical Deformation and Pre-Deformation Control for Three Super High-Rise Buildings

Abstract

The cumulative problem of vertical deformation for super high-rise buildings during construction becomes more significant as the height of structure continue to increase nowadays, for which the investigation of the characteristics of the vertical deformation is worth conducting. First, the technique of simulation of the construction process for super high-rise buildings was developed systematically, with which simulation of construction of the three typical high-rise buildings was conducted. The effect of concrete creep, shrinkage and leveling during construction were investigated and the characteristics of the vertical deformation revealed. Furthermore, a method of pre-deformation for super high-rise buildings was presented with deformation compensation stepwise. The total vertical displacement and the relative deformation between the inner core tube and the outer steel frame were chosen as the control targets in the method, which can be used to address the cumulative problem of vertical deformation and to provide technical support for deformation control in construction of super high-rise buildings.

Staged‐construction analysis of high‐rise buildings: A literature review and future perspectives

“…11,26,31 While studies on DAS effects on member internal forces were conducted to provide a more accurate analysis of HRB. 3,7,19,28,32 Studies on damages to non-structural elements by DAS were needed to examine some serviceability problems that occurred in existing HRB. 16,30,33 The research work related to the structural stability was focused on HRB with plan irregularity.…”

Review on field monitoring of high‐rise structures

“…In the current practice of high-rise structural construction, the differential settlement of the structural members is controlled or compensated using an empirical value of predetermined height in the next construction stage; thus, the elevation of the member meets the design requirements via the FE construction stage analysis following the real construction sequence. 127 Construction stage analysis for a high-rise structure can be classified into forward and backward analyses according to the analysis sequence. 128 Forward analysis follows the real construction sequence.…”

Analysis on interstory drift of high-rise residential quasi-megastructure

“…Almost in all the major cities in Asian countries, residential buildings are characterized with high-rise and high density (Smith and Willford, 2010). The planning of high-rise buildings is examined to alleviate both extremely crowded urban environments (Fan et al, 2013). Under this circumstance, constructing the residential structures with the most economic rationality is particularly important.…”
