Yong Hao,Feng Chen,Yun-hui Han,Xue-qian Hao,Chun-hui Du,Qiu-yu Ding 대한토목학회 2024 KSCE Journal of Civil Engineering Vol.28 No.2

In order to improve the seismic performance of vertical setback steel bundled-tube structure and meet the dynamic multi-objective requirements of seismic performance-based design, the optimization effects under rare earthquakes on the zone of fortification intensity 7 and 8 in China are researched by improving members stiffness and adding dampers in the weak parts of structure, based on dynamic elastic-plastic analysis. The results show that: 1) Under rare earthquakes on the zone of fortification intensity 7, increasing the stiffness of weak skirt beam can improve the seismic performance of spiral and symmetrical setback structure; 2) For the spiral setback structure, under rare earthquakes on the zone of fortification intensity 7, the damper can only be arranged at the junction of the first layer of the setback frame unit and the frame unit without setback. However, under rare earthquakes on the zone of fortification intensity 8, it is not advisable to install dampers at the weak areas; 3) After incorporating dampers at the weak areas of symmetrical setback structure, the optimized members experienced a reduction in stress levels, significantly decreased the inter-layer displacement angles with a maximum reduction of 43%, and the optimization effect is significant.

Member capacity-based progressive collapse analysis of transmission towers under wind load

Yong-Quan Li,Yong Chen,Guohui Shen,Wenjuan Lou,Weijian Zhao,Hao Wang 한국풍공학회 2021 Wind and Structures, An International Journal (WAS Vol.33 No.4

The wind-induced collapse of transmission towers has raised many concerns. Progressive collapse analysis is recognized as a promising method for the assessment of the collapse-resistant capacity of the transmission tower. The finite element model of an actual transmission tower is firstly built for the analysis, in which the dynamic behavior of the member in failure is taken into account to be in accord with the actual tower collapse. The analysis considering the main design load cases is conducted in advance to determine the case under which the tower has the potential to collapse. The incremental dynamic analysis in association with the explicit time integration algorithm is employed to perform a progressive collapse analysis, where the wind loads are simulated by using the linear filtering method, and the developed failure criterion with axial force and bending moment involved is based on the stability bearing capacity of the members. It is found the tower collapse begins with the horizontal bracing member near the waist. Then, the adjacent members, including the leg members, fail sequentially, and the tower collapses eventually with a shear-type failure. The demand to capacity ratio (DCR) in terms of bearing capacity of the member is defined to quantify the structural behavior, the location of the member that has the potential to fail, and when the initial failure occurs are thereby identified. It is concluded that compared to the member capacity-based analysis, the ultimate strain-based analysis, which is most likely to be an inelastic dynamic analysis permitting a large deformation, may overestimate the bearing capacity of the structure in wind-induced collapse.

A Low-cost IMU/GNSS Cooperative Positioning Method for VANETs in the Urban Environments

Yong Hao,Feng Shen 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.12

It is important to know the key problem of the emerging intelligent transportation systems –relative position, especially in the collision warning and speeds advisory. However, the commercial Global Satellite Navigation Systems (GNSS) receiver cannot up to the standard of these purpose. Fortunately, using Cooperative Positioning (CP) techniques to share the GNSS measurements between vehicles can largely improve the performance of relative positioning in a vehicular ad hoc network (VANET). But in urban environments, the reduced quality or complete unavailability of GNSS measurements challenge the effectiveness of any CP algorithm. In this paper, a new improved tight CP technique is proposed which adds the measurements from low cost inertial sensors. In the enhanced CP method proposed here, vehicles communicate their GPS measurements and inertial measurement unit (IMU) data, and each vehicle fuses local GPS and IMU measurements and those of the neighbours. Experimental results show that the new tight integration CP method can enhance the relative positioning in low GPS coverage environment, such as in very dense urban areas and tunnels.

MicroRNAs (miRNAs) are endogenous non-coding genes that participate in post-transcription regulation by either degrading mRNA or blocking its translation. It is considered to be very important in regulating insect development and metamorphosis. Insects are the largest group of animals and are extremely valuable in biological and agriculture research. Insects are also important pests to human health and agriculture, and efforts are necessary protect both humans and plants from disease and damage. Despite their importance, insects lag behind mammals, nematodes, and plants in miRNA research. At present, only 279 insect miRNAs have been identified from Drosophila melanogaster, Anopheles gambiae, Apis mellifera, Bombyx mori, and D. pseudoobscura in miRBase, and most of these miRNAs were computationally predicted without experimental validation. Functional analysis of insect miRNAs has only been conducted in D. melanogaster.

Yong Hao,Tian-jiao Han,Hang-fei Wu,Hua-hai Dong,Yin Zhou,Chun-hui Du,Yun-hui Han 대한토목학회 2024 KSCE Journal of Civil Engineering Vol.28 No.4

The wind-induced interference effects existing during the construction of a building group were studied in the context of the Zhangjiakou Olympic Sports Center project. Based on CFD numerical simulations, 120 and 96 different working conditions during construction of a swimming pool and speed skating hall were simulated and analyzed respectively, and the numerical simulation results were found to be in high agreement with the wind tunnel test results, which verified the accuracy and feasibility of the numerical simulation. By comparing the wind-induced interference effects of the surrounding buildings on the swimming pool and the speed skating hall during different construction periods, it was found that the swimming pool was more affected by the interference of the surrounding buildings than the speed skating hall, and the wall area was more affected by the interference than the roof area. The wind-induced response of the swimming pool structure during different construction periods was analyzed, and it was found that the interference effect under some working conditions had a greater impact on the structural stress, and it was suggested that the wind interference effect brought about by the construction of the building should not be ignored in such projects.

연구논문 : 중국 민족구역자치지역의 입법변통권에 관한 연구 -연변조선족자치주를 중심으로-

채영호 ( Yong Hao Cai ) 국제헌법학회,한국학회 2013 世界憲法硏究 Vol.19 No.3

다민족국가인 중국은 민족구역자치제도를 통하여 민족문제를 해결하고 있다. 민족구역자치는 소수민족지역에서의 인민주권원리의 실현으로서 그 관건은 자치권에 있다. 민족구역자치지역은 일반 지방에 비하여 광범위한 자치권을 갖고 있지만 그 중 제일 중요한 자치권은 입법변통권이라 하겠다. 즉 민족구역자치지역은 본 지방 민족의 정치, 경제와 문화의 특성에 근거하여 자치조례와단행조례를 제정할 권한이 있고, 자치조례와 단행조례는 법률, 행정법규와 지방성법규의 규정에 관하여 변통규정을 할 수 있다. 민족구역자치지역의 자치입법의 역사를 보면 입법변통권은 주로 소수민족의 전통 및 민족구역자치지역의 낙후한 현실과 국가 법률 간의 차이를 완화하는데 활용되었고, 해당 지방발전의 추진에는 작용이 미약하여 30여년이 지난 오늘에 이르러서도 민족구역자치지역과 일반 지방과의 정치, 경제, 문화 간의 차이는 여전히 크다. 민족구역자치지역의 이러한 현황을 개변하고 입법변통권을 활용하여 민족구역자치지역의 정치, 경제, 문화의 전면적인 발전을 추진하려면 중국 현행 입법기관의 관본위사상, 변통입법심사에 있어서의 개인책임제, 인민대표대회 상무위원회의 구성으로 인한 이익관계와 민족구역자치지역 법제건설의 낙후한 현실 등 문제점들을 해결하여야 한다. As a multinational country, China solves national problems through the system of regional national autonomy. As the system of implementation of the people sovereignty principle in minority local, regional national autonomy`s point is the exercise of autonomy. Regional national autonomy enjoyed broader autonomy than general places, and one of the most important autonomies is the legislation accommodation power. According to the political, economic and cultural characteristics, regional national autonomy has the right to develop autonomy and special regulations which can make variable regulations of laws, administrative regulations and local regulations. From the history of autonomy legislation of regional national autonomy, legislative accommodation power is mainly applied to the right of inheriting the ethnic traditional, easing the gap between behind reality of regional national autonomy and the country`s advanced laws, but its role is very small as for the local economic development. Despite more than 30 years, differences of political, economic and cultural remain large between general local and regional national autonomy. Making flexible use of legislation accommodation power can change present situation of regional national autonomy. However, making flexible use of legislation accommodation power should eliminate China`s current legislature`s official thinking, accommodate individual responsible system of legislation investigation, erase interest relation of forming the Standing Committee of the National People`s Congress, and carry forward legal system construction of regional national autonomy, and so on.

중국 인민대표대회 선거제도의 발전과정과 문제점

채영호 ( Yong Hao Cai ) 건국대학교 법학연구소 2015 一鑑法學 Vol.0 No.30

According to the Constitution of the People’s Republic of China,, all power in the People’s Republic of China belongs to the people. The organs which the people exercise state power through are the National People’s Congress and the local people’s congresses at various levels. All of the people’s congresses are constituted through democratic election. They are responsible for the people and accept their supervision. China’s first Electoral Law was enacted in 1953. After the development of more than 60 years, electoral system of the people’s congress formed. Through several revisions of electoral law, it has made great progress in some respects. Such as, the universality of deputy, balance between rural and urban areas, the relationship of deputy and constituents, the electoral procedure. However, there are some existing problems. For example, electoral body’s week influence and supervision on deputy, insufficient understanding about candidates, not aggressive constituents, etc. Above problems are based on these reasons. The Constitution on the provisions of the ruling party is not perfect, and the implementation of elite democracy and exercise of deputy authority are inadequate, and so on. China should properly solve the problems on electoral system. Expanding the power of deputies who are elected through direct election, perfecting the removal system, and strengthening containment on deputy might be considered.
