Abstract
The stiffened top‐and‐seat angle connection is widely used in earthquake‐prone areas, and additional tensile bolts on angles' column leg effectively improve its bending behavior. However, such design and construction are not governed by any regulations. It is urgent to figure out the mechanical behavior and develop accurate theoretical methods. Based on the component method, this paper first conducted an experimental study on the extracted cruciform stubs with four bolts per row. It compared the tensile properties and damage modes for different thicknesses. After that, the further parametric analysis compared the impact of stub thickness, bolt arrangement, and whether or not the bolt was pretensioned after validation. Stub thickness and bolt gauge were observed with a greater impact than the bolt distance on the plastic resistance. Furthermore, a prediction model for the plastic resistance of the cruciform stub with four bolts per row is proposed by integrating approaches for classic stiffened and unstiffened angles.
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.
