Verification of structural performance of connections between reinforced concrete shear walls and outriggers in high‐rise buildings

Abstract

The outrigger and belt truss system is the most commonly used lateral load‐resisting system for high‐rise buildings in which the external mega columns and core walls are connected via outriggers and belt trusses. The shear studs, which are used for the connections between the outriggers and the core walls, are subjected to pull‐out loading because of the lateral load. Although various types of shear studs have been developed based on analytical and experimental studies, most previous studies on the behavior and strength of shear studs have been based on push‐out tests. It is necessary to verify the structural performance of shear studs subjected to pull‐out loading before their field installation at the connections in the structural system of high‐rise buildings. In this study, experiments were conducted on full‐scale pull‐out test specimens made of materials having the same strength as those used in an actual high‐rise building structure. The experimental results show that the shear strength of the connection can be improved by approximately 7.9% using double‐headed studs instead of normal‐strength studs.

Distribution Technique of Green Material List for High-Rise Building Engineering in BIM Technology

“…It is required to fully consider various stress conditions of the structure during construction and material selection, ensure that the structure has sufficient stiffness, strength, and stability, and strictly control the horizontal displacement of the structure. In high-rise building structures, the horizontal load presents marginal increasing effect with the increase of height, and the damage force of horizontal load and earthquake is large [11,12]. At present, there are four common structural systems of high-rise buildings, as shown in Figure 2: According to Figure 2, the common structural systems of high-rise buildings mainly include frame structure system, shear wall structure system, frame shear wall structure system, and tube structure system [13].…”

Dual-Objective Control of Maximum and Residual Drift Ratios of Super-Tall Buildings Based on Self-Centering Energy Dissipation Outriggers

“…Regarding the horizontal components (e.g., coupling beam and outrigger), highperformance energy dissipation components can be introduced to dissipate plastic energy, and reduce damage to the vertical components to ensure the seismic performance of the main structure (Yang et al, 2016;Ding et al, 2018). Frame-core tube-outrigger systems, which are typical hybrid lateral loadresisting systems, and have been widely used in modern super-tall buildings (Park and Oh, 2018;Zhang et al, 2018;Shim et al, 2019;Alhaddad et al, 2020;Huang et al, 2021). In this system, the outrigger is typically designed as an energy dissipation component that is elastic under the service level earthquake (SLE) and the design basis earthquake (DBE).…”
