Numerical Study of the Nonlinear Dynamic Behaviour of Reinforced Concrete Cooling Towers under Earthquake Excitation
Advances in Structural Engineering - Tập 9 Số 3 - Trang 433-442 - 2006
Reinforced concrete cooling towers of hyperbolic shell configuration find
widespread application in utilities engaged in the production of electric power.
In designing critical civil infrastructure of this type, it is imperative to
consider all of the possible loading conditions that the cooling tower may
experience. One important loading condition in many nations is that of
earthquake excitation,...
Seismic Performance Upgrading for Underground Structures by Introducing Shear Panel Dampers
Advances in Structural Engineering - Tập 17 Số 9 - Trang 1343-1357 - 2014
A new method of upgrading seismic performance for underground structures is
proposed in this paper. Both single-story and double-story underground subway
stations are studied. Using the famous single-story Daikai Station model, by
which the reliability of the numerical model is verified, seismic efficiency of
Shear Panel Damper (SPD) in underground structures is proven. Then, in order to
design ap...
Seismic performance of framed underground structures with self-centering energy-dissipation column base
Advances in Structural Engineering - Tập 22 Số 13 - Trang 2809-2822 - 2019
For the development of underground structures toward large-scale, long-span, and
complex structural styles, comprehensive seismic mitigation and controlling
measures that consider reducing internal forces together with controlling
lateral structural deformation and upgrading energy consumption are significant
for improving seismic performance and enhancing resilience of underground
structure. For ...
Effect of screw spacing on behavior of axially loaded back-to-back cold-formed steel built-up channel sections
Advances in Structural Engineering - Tập 21 Số 3 - Trang 474-487 - 2018
In cold-formed steel structures, such as trusses, wall frames, and portal
frames, the use of back-to-back built-up cold-formed steel channel sections for
the column members is becoming increasingly popular. In such an arrangement,
intermediate fasteners at discrete points along the length prevent the
individual channel sections from buckling independently. Current guidance by the
American Iron and...
Initial Stiffness of Reinforced Concrete Columns with Moderate Aspect Ratios
Advances in Structural Engineering - Tập 15 Số 2 - Trang 265-276 - 2012
The estimation of the initial stiffness of columns subjected to seismic loadings
has long been a matter of considerable uncertainty. This paper reports a study
that is devoted to addressing this uncertainty by developing a rational method
to determine the initial stiffness of RC columns when subjected to seismic
loads. A comprehensive parametric study based on a proposed method is initially
carrie...
Tension Force and Structural Parameter Identification of Bridge Cables
Advances in Structural Engineering - Tập 15 Số 6 - Trang 983-995 - 2012
Vibration measurement is one of the most widely used methods for tension
evaluation and condition assessment of stay cables in cable-stayed bridges. In
the existing practice, the tension force of a cable is identified from the
measured modal frequencies with the use of the taut string theory or empirical
formulae, by assuming pre-determined structural parameters (geometric and
material parameters)...
Probabilistic corrosion fatigue life assessment of a suspension bridge instrumented with long-term structural health monitoring system
Advances in Structural Engineering - Tập 20 Số 5 - Trang 674-681 - 2017
The long-term performance of engineering structures in a corrosive environment
will be significantly affected by the coupled action of corrosion and fatigue.
In this article, a probabilistic corrosion fatigue analytical model is proposed
by taking into account the effects of corrosion-induced reduction of the
cross-sectional area and deterioration of the fatigue strength of structural
components. ...
Hybrid fibre-reinforced polymer–timber thin-walled structural members
Advances in Structural Engineering - Tập 21 Số 9 - Trang 1409-1417 - 2018
The increasing interest in timber as a sustainable construction material has led
to the development of a new type of structures referred to as ‘hybrid
fibre-reinforced polymer–timber thin-walled structures’. In these structures,
thin layers of fibre-reinforced polymer are combined with timber veneers to
create high-performance, lightweight and easy-to-construct structural members.
This new type of...
Performance Testing and Cyclic Behavior of Buckling-Restrained Braces with H Cross Section Unrestrained Segments
Advances in Structural Engineering - Tập 17 Số 5 - Trang 677-692 - 2014
The hysteretic behavior of four buckling-restrained braces (BRBs) with H cross
section unrestrained segment was tested under cyclic load. The transformation of
the unrestrained segment's section from crisscross shape to H shape can improve
the moment-resistance capacity of unrestrained segment significantly and avoid
buckling instability of unrestrained segment effectively due to evident
stiffness...
Recent progress in buckling restrained braces: A review on material development and selection
Advances in Structural Engineering - Tập 25 Số 7 - Trang 1549-1564 - 2022
Passive energy dissipation devices are a widely accepted solution used to
improve the response of the structures under seismic conditions. While several
types of passive energy dissipation elements have been proposed for replaceable
elements, buckling restrained braces (BRB) was one of the most effective
replaceable elements which has been used to retrofit frame structures in the
past few years. A...
