Sliding Behavior Monitoring of a Deep Seated Landslide with Differential Interferometric Synthetic Aperture Radar, MEMS Tiltmeter and Unmanned Vehicle Images Kuo-Lung Wang, Yo-Ming Hsieh, Jun-Ting Lin Ming-Hsiang Hsi Pages 1045-1051 (2017 Proceedings the 34rd ISARC, Taipei, Taiwan, ISBN 978-80-263-1371-7, ISSN 2413-5844) Abstract: is common issue in Taiwan more than 70% area this island mountainous land. Typhoons earthquakes attack every year even by month. People lost their lives,...
The maintenance planning of deteriorating bridges is to find a balance between obtained performance and incurred cost. Because the horizon spans tens years, certain amount uncertainty inherent in forecasting process costs effects actions. This paper proposes multiobjective simulation optimization framework establish trade-off among expected values life-cycle cost measures. information, represented as Pareto front, gives planners sufficient flexibility respond various needs. performed by...
This paper discusses how small-strain stiffness and some aspects of the yield surface affect finite-element predictions excavation responses, including wall ground deformations. By using in-house-developed constitutive model SC1SS, it is possible to isolate quantify impacts brought about by selected soil behavior. has been validated reasonably Taipei silty clay deep excavations in such soil. study shows that ignoring can overestimate deformations as much 80%, leading conservative costly...
Development of BIM-Based Real-time Evacuation and Rescue System for Complex Buildings Min-Yuan Cheng, Kuan-Chang Chiu, Yo-Ming Hsieh, I-Tung Yang Jui-Sheng Chou Pages 999-1008 (2016 Proceedings the 33rd ISARC, Auburn, USA, ISBN 978-1-5108-2992-3, ISSN 2413-5844) Abstract: With architectural environment is constantly changing such as high-rise buildings, high-ceilinged space, special space constructed, thus fire disasters are becoming diverse difficult to predict. Therefore, development...
Parameter or system identification is a useful tool in civil engineering. They have wide applications across many disciplines. However, due to the lack of general-purpose tools for such analyses, researchers need develop their own codes with duplicated efforts. Yet, it sometimes difficult adopt other people's code different modeling methods used. Thus, there resolve problems this kind. This paper describes purpose. The has three features. First, uses cloud-computing technology provide...
This paper describes a numerical study of drained pressuremeter tests in sand using one-dimensional finite-element method conjunction with an advanced soil model MIT-S1, and input parameters corresponding to Toyoura sand. is capable describing realistically the transitions peak shear strength cohesionless soils that occur due changes void ratio confining pressure. The predicted strengths can be normalized, at least approximately, by introducing state parameter references initial (preshear)...
This paper presents a study on excavation-induced deformation characteristics of ground and adjacent building using three-dimensional (3D) decoupled simulations. A analytical technique is proposed to enhance the consideration both 3D nonlinear soil behavior inelastic structure responses. The excavation effects structure’s responses are simulated by two separate programs: PLAXIS for SAP 2000 structure. Two models bridged simple iteration scheme. well-documented case history low-rise framed...
Abstract When geo‐materials, such as soil, gravelly soil and soft rocks, are loaded by shear stress, they frequently exhibit volumetric deformation, either dilation or compression, that cannot be modeled conventional elasticity of isotropic material. This study aims, using few parameters possible, to develop a material model designed simulate the main deformation geo‐materials. A constitutive based on concept shear‐induced anisotropic degradation is proposed. The proposed characterized...
Localization inside Tunnels Using Machine Vision Y.M. Hsieh, Y.C. Liao Pages 860-867 (2014 Proceedings of the 31st ISARC, Sydney, Australia, ISBN 978-0-646-59711-9, ISSN 2413-5844) Abstract: (position tracking) tunnels is difficult. GPS signal not available tunnels, and installation wireless access points expensive. In this work, we propose use machine vision for localization in tunnels. The advantage such approach that it requires no any infrastructure, needed with radio triangulation...
Parametric studies in parallel-computing is often considered as an "embarrassingly parallel" computation task that can be trivially parallelized and yield good parallel efficiency. However, this paper shows the efficiency of such analyses further improved by proposed scheme typical cluster setups using commodity PC hardware. Numerical experiments show finite element 81.6% peak disk usage reduced 83.1%. The for enhancing performance readily extended to design optimization problems, which has...
