Manufactured by laser cutting technology with planar steel plates, the plate members have
significant advantages in efficiency, customization, and transportation. These advantages …

This paper is a survey of the literature about the nonlinear updating process. It is focused on
the computation of the difference between the numerical model and the reference data as …

In a space structure, each connection can be subjected to different ratios of axial force to
bending moment. In this paper, a test procedure was presented that enables realistic testing …

In the present experimental study, 12 specimens were tested to assess and quantify the
effects of bolt tightness on the overall behavior of a bolt-ball joint under uniaxial loading. A …

To achieve light weight, high load-carrying capacity, and corrosion resistance, a novel
hybrid FRP-aluminum space truss system is proposed in detail. An advanced pretightened …

针对结构有限元分析中模型精度低的问题, 提出了响应面优化的模型修正方法.
利用优化拉丁方试验设计样本点, F 值检验筛选出修正参数构造不完全4 阶多项式响应面并检验 …

Mechanical imperfections are almost inevitable in large-span spatial domes with hundreds
of members and joints. The lack of fit in members is the most common form of imperfections …

A comprehensive finite element (FE) model of bolt-ball joint, as called MERO joint, is
presented in this paper for a double layer grid structure. In double layer grids, the main …

This study proposes a method for updating the finite element model of crooked members in
grid structures based on 3D scanning data. The crooked member is modeled using the multi …

The mechanical properties of joints may impact a system's static and dynamic behavior.
Since connections are usually complex, modeling their geometric details could take time …
