“…One of the HRB construction challenges is to try to keep slabs at their design elevations in spite of the gradual shortening of columns and walls (as discussed in Section 3). The numerical simulation of this issue was discussed by previous studies, [1][2][3][4] while field investigations for it were performed by other studies. 8,12,13,19 The aforementioned studies have shown that the resultant deformations and straining actions will be affected by the method by which this height loss is compensated.…”

“…3,30,41 On the other hand, HRBs were reported to be greatly affected by SCA. [1][2][3][8][9][10]12 Lack of provisions may be also attributed to the limited number of studies that linked problems in structures (such as cracks in elements or excessive DAS) to the failure to conduct SCA. 16,33,41,65,92 One study by Ha and Lee 16 showed a cracking pattern in slabs and beams of an HRB in Korea due to improper structural analysis that poorly estimated DAS.…”

SummaryStaged‐construction analysis (SCA) has recently become a noticeable trend for estimating the design forces and deformations for high‐rise buildings (HRBs). SCA is a nonlinear step‐by‐step analysis that simulates the construction activities and conditions. It is a numerical simulation that considers loading history during construction, time‐dependent material behavior, environmental conditions, and any special measures taken by contractors to limit differential axial shortening during the construction process. However, building codes and guidelines do not provide adequate provisions that clearly identify how to approach this type of analysis. This paper presents a comprehensive state‐of‐the‐art review on how SCA was previously adopted in theoretical research and how it was applied in real buildings. It begins by critically reviewing different research work on SCA. Afterward, the paper puts forward the recent fundamentals of conducting SCA. Then, a series of studies about verifying SCA as practical analysis procedure using field measurements are then presented. In addition, the current paper reviews how SCA can specifically affect post‐tension slabs. Based on this review, several recommendations are provided to help in shaping the future code provisions, add to the development of recent practices, and inspire future research. The conducted review concludes that more investigations should be performed to better understand the effect of considering SCA on the deformations and design forces during HRB analysis.

“…Staged construction and one step investigation for reinforced concrete (RC) tall structure with several systems that endure lateral loads was carried out to satisfy both service and ultimate state design [17]. A 16-story structure with plain frame, tube in tube construction with tubes in the middle and core, coupled with the tube mega frame, was subjected to wind and seismic loads using ETABS to conduct a comparative analysis [18].…”

In recent years, there has been a noticeable increase in demand for high-rise building development with increased slenderness and decreased building weight [1]. Due to population growth, there has been more construction, fast industrialization, and the concomitant lack of land, particularly in urban areas. The consequences of lateral stresses deteriorate with increasing structural height. Building high-rise structures requires taking into account lateral loads in addition to the gravity force, such as earthquake and wind loads [2].

“…A computational method was used by Dinar et al (2014) [6] and Correia & Lobo (2017) [5] to investigate the impact of sequencial self-weight on construction. Ha et al (2017) [8] 2 developed an algorithm for the construction stage to assess the outcomes with a laser survey and advised taking into account the time-dependent effect of the concrete during the design stage of tall buildings. An improved correction factor approach was proposed by Afshari et al (2017) [1] .…”

Construction Sequence Analysis (CSA) is a method that follows real-time onsite construction practices like construction sequence, sequential loading, and timing. Properties of concrete, like Creep and shrinkage are time-dependent properties of concrete, so it is crucial to determine the period up to which critical responses are received during a building's life. This study observes the different responses of structural members seeing the long-term effect of concrete properties for up to 50 years, cohesive to the standard lifespan of RC structures in India. The study derives the most critical time during the entire life of the building using the CSA method. According to this study, 98% to 99% of the 50 thyear responses are attained within 10950 days after applying live load. The study recommends analysing RC structures for 10950 days using the CSA method instead of ending at the time of live load application or continuing analysis up to 50 years. It is important to know the limit of total storeys above which the behaviour of vertical members becomes vulnerable in RC buildings. The study also determines the critical storey limit of RC moment frame building over which the CSA method must be utilised. Hence, this study uses the CSA and Linear Static Analysis method to analyse 12 RC building models of various beam spans and total storeys. The study concludes that the CSA method should be mandatory for buildings with more than nine stories.
