“…The differential axial shortening of vertical members may not affect these elements to any great extent; however, horizontal elements, such as beams and slabs, can be severely affected. [124][125][126] Therefore, the vertical displacement (or settlement) of the foundation and superstructure has been a primary concern of the structural condition throughout the construction stage. 30 Strain monitoring of main structural components is essential for the construction of high-rise structures.…”

Structural health monitoring (SHM) has been developed and applied to bridge structures since the early 1980s. Numerous approaches and techniques have been proposed and applied to supertall structures during the recent decade. This paper reviews the SHM techniques and applications in supertall structures. The vibration analysis techniques, seismic effect monitoring, wind effect monitoring, comfort assessment, temperature effect monitoring, and construction monitoring of high-rise structures are described and summarised. The latest developments in codification and standardisation in SHM are also introduced.

“…For supertall structures, the vertical displacement responses (or settlement) of the foundation and superstructure have been a primary concern of structural condition at different construction stages since the structural system, material properties, loads and actions in the construction phase are time varying and totally different from those in the service phase (Yang et al 2012). The changing loadings and environmental factors make the construction positioning very difficult and may make the constructed structure deviate from the design.…”

Excessive and unexpected settlement of supertall buildings during the construction stage may affect structural safety. Floor settlement monitoring is imperative during the structural construction. The current practice is to measure floor settlement within a specific time frame and then compensate for the elevation error in the next construction stage. This posterior manner is inaccurate because it does not take account of measurement error and the real settlement in the next construction stage. This paper presents a Kalman filter based settlement monitoring approach with the aid of forward construction stage analysis. The settlement of floors in the next stage is predicted with the forward construction stage analysis. Consequently the elevation of the floor to be constructed can be pre-determined. The proposed method is demonstrated through construction settlement monitoring of the 632-m tall Shanghai Tower. The structure will be the tallest supertall building of China upon completed in 2014. It shows that this method can improve the accuracy of pre-determined elevation of supertall buildings.

“…Kim et al (2010) and Park et al (2013) proposed a simplified analysis method with lumped construction sequences for the column shortening of buildings. Yet the precise construction duration of each floor has not been considered in most research so far (Moragaspitiya et al 2010), and publications regarding building over 400 m high are few (Yang et al 2012).…”

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.
