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
Saeid Sabouri‐Ghomi, Farhad Abedi Nik, Ali Roufegarinejad, Mark A. Bradford
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 ex...... hiện toàn bộ
Seismic Performance Upgrading for Underground Structures by Introducing Shear Panel Dampers
Advances in Structural Engineering - Tập 17 Số 9 - Trang 1343-1357 - 2014
Zhiyi Chen, Wei Chen, Guoqiang Bian
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 ...... hiện toàn bộ
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
Zhiyi Chen, Yu Zhou
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 struct...... hiện toàn bộ
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
Tina Chui Huon Ting, Krishanu Roy, Hieng Ho Lau, James B.P. Lim
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...... hiện toàn bộ
Initial Stiffness of Reinforced Concrete Columns with Moderate Aspect Ratios
Advances in Structural Engineering - Tập 15 Số 2 - Trang 265-276 - 2012
Cao Thanh Ngoc Tran, Bing Li
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 initial...... hiện toàn bộ
Tension Force and Structural Parameter Identification of Bridge Cables
Advances in Structural Engineering - Tập 15 Số 6 - Trang 983-995 - 2012
W.Y. Liao, Yi‐Qing Ni, Gang Zheng
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 pa...... hiện toàn bộ
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
X. W. Ye, T. Liu, YQ Ni
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 comp...... hiện toàn bộ
Hybrid fibre-reinforced polymer–timber thin-walled structural members
Advances in Structural Engineering - Tập 21 Số 9 - Trang 1409-1417 - 2018
Dilum Fernando, J.G. Teng, Joseph M. Gattas, Michael Heitzmann
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 ne...... hiện toàn bộ
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
Mingming Jia, Dagang Lü, Lin Sun, Sumei Zhang
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 s...... hiện toàn bộ
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
Yan Zhuge, Xing Ma, Jun‐Jie Zeng
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...... hiện toàn bộ
