Analysis of constructive effect and soil-structure interaction in tall building projects with shallow foundations on sandy soils

Abstract

The influence of incremental constructive effects (IE) and soil-structure interaction (SSI) on high-rise buildings of reinforced concrete with shallow foundations on sandy soils were analyzed. IE and SSI evaluations were carried out by the parameters of global instability, maximum horizontal displacements, foundation loads, and settlements of a symmetrical and non-symmetrical plant of a 23-storey building For the analysis of the IE, the variation of the modulus of elasticity was considered over time along with the phases of application of loads in the building. For ISS analysis, the continuous medium was considered, and the calculation model considers a multi-spring-mass system under the foundation of the building. The results show a significant redistribution in the foundation efforts and suggest that a failure in considering these effects along with the structure can lead to projects that do not meet the standard specifications regarding stability parameters and overall structure displacements.

Influence of soil-structure interaction modeling on the behavior of multi-story plane steel frames with shallow footing foundations

“…The development of computer programs made it possible to model soil-structure interaction problems, and consequently, to obtain more accurate results about the stability of a structural system. Several soil-structure interactions methods for numerical modeling, indicating their benefits and limitations, as well as the computer programs available for such analysis are proposed in the literature, to quote Ritter et al (2020), Pavan et al (2014), Marques et al (2021), Ada and Ayvaz (2019), Ingle (2001, 2008), Chore et al (2009), Saha et al (2020), Dutta and Roy (2002), Garg and Hora (2012), Yesane et al, (2016) and Darbandsari and Kashani (2018).…”
