Abstract
To investigate the effect of soil‐structure interaction (SSI) on the seismic response of frame buildings on collapsible loess, the secondary development of Abaqus was used to realize the embedding of the unified strength theory constitutive model. Meanwhile, a new nonlinear elastic model generated by the unified strength theory (b, the failure criterion parameter in the unified strength theory, equals 0.5) was developed. Seven‐ and nine‐story frame buildings were selected as engineering examples in this study. The outcomes indicate that the nonlinear behavior of the loess–pile has a significant effect on the dynamic interaction of both group pile foundations and the superstructure under strong earthquakes. This results in an amplification of the displacement response and a reduction in inter‐story shear force. As the foundation soil becomes softer, the K‐type distribution of both peak accelerations and inter‐story displacements along height becomes more obvious in general.
期刊介绍：
The Structural Design of Tall and Special Buildings provides structural engineers and contractors with a detailed written presentation of innovative structural engineering and construction practices for tall and special buildings. It also presents applied research on new materials or analysis methods that can directly benefit structural engineers involved in the design of tall and special buildings. The editor''s policy is to maintain a reasonable balance between papers from design engineers and from research workers so that the Journal will be useful to both groups. The problems in this field and their solutions are international in character and require a knowledge of several traditional disciplines and the Journal will reflect this.
The main subject of the Journal is the structural design and construction of tall and special buildings. The basic definition of a tall building, in the context of the Journal audience, is a structure that is equal to or greater than 50 meters (165 feet) in height, or 14 stories or greater. A special building is one with unique architectural or structural characteristics.
However, manuscripts dealing with chimneys, water towers, silos, cooling towers, and pools will generally not be considered for review. The journal will present papers on new innovative structural systems, materials and methods of analysis.
