Performance-Based Multi-Objective Optimization of Four-Limb CFST Lattice Columns Open
In this paper, the low-cycle reciprocating load test was carried out on four-limb concrete-filled steel tubular (CFST) lattice columns with different slenderness ratios and axial compression ratios, and the seismic performance was studied.…

Effect of vertical stiffeners on the seismic performance of T‐shaped CFST column to steel beam joint Open
Summary Special‐shaped concrete‐filled steel tubular (SCFST) columns have recently been developed for efficient steel‐concrete composite construction. In this study, a novel vertical stiffener joint for the SCFST column and steel beam fram…

Construction Activity Analysis of Workers Based on Human Posture Estimation Information Open
Identifying workers’ construction activities or behaviors can enable managers to better monitor labor efficiency and construction progress. However, current activity analysis methods for construction workers rely solely on manual observati…

Vibration Serviceability of Large-Span Steel–Concrete Composite Beam with Precast Hollow Core Slabs Under Walking Impact Open
A large-span steel–concrete composite beam with precast hollow core slabs (CBHCSs) is a relatively new floor structure that can be applied to various long-span structures. However, human-induced vibrations may present serviceability issues…

Experimental and numerical investigation on the seismic behavior of plane frames with special-shaped concrete-filled steel tubular columns Open
The seismic behavior of (plane) frames with special-shaped concrete-filled steel tubular (CFST) columns (SCFSTFs), H-shaped steel beams, and exterior diaphragm connections was investigated experimentally and numerically in this study. Doub…

Disturbance function for soil disturbed state strength based on X-ray computed tomography triaxial test Open
Soil is a porous, multiphase, and loose medium, which is prone to serious disturbance by the activity of biological livings, accompanied with cracks and macro pores. These phenomena greatly affect the strength of soil and the degradation o…

Bond Behavior of Reinforcing Steel Bars in Thermal Insulation Concrete Exposed to Freeze-Thaw Cycles Open
An experimental study on the bond behavior of reinforcing steel bars in thermal insulation concrete (TIC) mixed with glazed hollow beads (GHBs) and exposed to freeze-thaw (F-T) cycles was carried out. In order to investigate the effects of…
View article: Tension Test for Axially Vibrated Prestressing Fine‐Rolled Screw‐Threaded Steel Bars Based on Thread‐Contact Connection
Tension Test for Axially Vibrated Prestressing Fine‐Rolled Screw‐Threaded Steel Bars Based on Thread‐Contact Connection Open
The interface between anchor plate and anchorage nut can be considered as a coupling spring whose stiffness is essentially the contact stiffness related to normal force at the contact surface, thus removing the usual assumption of fixed co…

Experimental Study on Variable‐Amplitude Fatigue of Welded Cross Plate‐Hollow Sphere Joints in Grid Structures Open
The fatigue stress amplitude of the welded cross plate‐hollow sphere joint (WCPHSJ) in a grid structure varies due to the random loading produced by suspending cranes. A total of 14 specimens considering three different types of WCPHSJs we…

Experimental Assessment on the Hysteretic Behavior of a Full‐Scale Traditional Chinese Timber Structure Using a Synchronous Loading Technique Open
In traditional Chinese timber structures, few tie beams were used between columns, and the column base was placed directly on a stone base. In order to study the hysteretic behavior of such structures, a full‐scale model was established. T…
