Stress-free-state based structural analysis and construction control theory for staged construction bridges - 2020
Shunquan Qin, Kai Wei, Jingxi Qin, Renan Yuan, Leiping Xu, Qilian Dan
AbstractStructural analysis and construction control of staged construction
process is a major subject for modern long-span bridges. This paper introduces
the concept of stress-free-state variable of structural elements and deduces the
mechanical equilibrium equations and geometric shape governing equations for
staged construction structures utilizing the minimum potential energy theorem.

Damage control of a twin-column pier with a replaceable steel shear link in a cap beam under transverse seismic motion Tập 2 Số 1 - 2021
Weiting Chen, Xuemeng Bai, Tong Xu, Shanshan Ke, Huimin Xie
AbstractThis paper proposes a novel twin-column pier with a steel shear link
(SSL) installed in the cap beam to reduce seismic damage in the transverse
direction. The SSL interrupts the rigid cap beam and relieves the coupled
deformation of the two columns. Benefits of the yieldable SSL in the event of a
strong earthquake are the longer effective deformation of a column and limited
axial compressi... hiện toàn bộ
Structural damage detection from dynamic responses of the bridge deck under a moving load using discrete wavelet transform Tập 3 Số 1
Seyyed Ali Mousavi Gavgani, Amir Ahmadnejad Zarnaghi, Sajad Heydari
AbstractEarly detection of structural damages and making necessary interventions
to repair them are one of the main challenges in structural health monitoring.
The wavelet transform is one of the common methods for this purpose, and its
efficiency is proven by many researchers. In the present study, this approach is
used to assess the performance of Sani-khani bridge with single and
multiple-damag... hiện toàn bộ
Finite element analysis of reinforced concrete curved box-girder bridges Tập 4 Số 1
Preeti Agarwal, Priyaranjan Pal, PK Mehta
AbstractThe study presents the design forces of simply supported single-cell
reinforced concrete (RC) curved box-girder bridges using a finite element method
(FEM) based CSiBridge v.20 software. An existing model has been used to validate
the present modelling approach. Models subjected to vertical loading, i.e., dead
load (DL) and Indian road congress live load (LL), are considered for
