Performance assessment of innovative seismic resilient steel knee braced frame

Tony T. Y. YANG,Yuanjie LI

《结构与土木工程前沿（英文）》 2016年第10卷第3期页码 291-302 doi: 10.1007/s11709-016-0340-3

摘要： Buckling restrained knee braced truss moment frame (BRKBTMF) is a novel and innovative steel structural system that utilizes the advantages of long-span trusses and dedicated structural fuses for seismic applications. Steel trusses are very economical and effective in spanning large distance. However, conventional steel trusses are typically not suitable for seismic application, due to its lack of ductility and poor energy dissipation capacity. BRKBTMF utilizes buckling restrained braces (BRBs) as the designated structural fuses to dissipate the sudden surge of earthquake energy. This allows the BRKBTMF to economically and efficiently create large span structural systems for seismic applications. In this paper, a prototype BRKBTMF office building located in Berkeley, California, USA, was designed using performance-based plastic design procedure. The seismic performance of the prototype building was assessed using the state-of-the-art finite element software, OpenSees. Detailed BRB hysteresis and advanced element removal technique was implemented. The modeling approach allows the simulation for the force-deformation response of the BRB and the force redistribution within the system after the BRBs fracture. The developed finite element model was analyzed using incremental dynamic analysis approach to quantify the seismic performance of BRKBTMF. The results show BRKBTMF has excellent seismic performance with well controlled structural responses and resistance against collapse. In addition, life cycle repair cost of BRKBTMF was assessed using the next-generation performance-based earthquake engineering framework. The results confirm that BRKBTMF can effectively control the structural and non-structural component damages and minimize the repair costs of the structure under different ranges of earthquake shaking intensities. This studies conclude that BRKBTMF is a viable and effective seismic force resisting system.

The Effect of TRIZ on Research Institute Innovation

He Liu,Qing-hai Yang,Xu Jin

《工程管理前沿（英文）》 2014年第1卷第4期页码 385-389 doi: 10.15302/J-FEM-2014059

摘要： With a background in improving independent innovation capabilities and building a world-class petroleum research institute, scientific innovation is the essence and basis of an innovative framework for a research institute, as well as the inexhaustible driving force for sustainable development. By introducing the theory of inventive problem solving (TRIZ) and combining it with CAI (computer aided innovation) technology, the Research Institute of Petroleum Exploration and Development established an adaptive innovative system by making experiments and fanning out from a point to an area gradually. This article takes the example of the innovative practices of the Department of Petroleum Equipment in Research Institute of Petroleum Exploration and Development, and introduces a building method for the innovative system based on technical innovation, enterprise culture, organizational structure, scheme, and people. It also summarizes the experiences and effects of improving innovative system upon scientific practice which can provide important guidance and reference significance for accelerating independent innovative capability.

Innovative piled raft foundations design using artificial neural network

Meisam RABIEI, Asskar Janalizadeh CHOOBBASTI

《结构与土木工程前沿（英文）》 2020年第14卷第1期页码 138-146 doi: 10.1007/s11709-019-0585-8

摘要： Studying the piled raft behavior has been the subject of many types of research in the field of geotechnical engineering. Several studies have been conducted to understand the behavior of these types of foundations, which are often used for uniform loading on the raft and piles with the same length, while generally the transition load from the upper structure to the foundation is non-uniform and the choice of uniform length for piles in the above model will not be optimally economic and practical. The most common method in identifying the behavior of piled rafts is the use of theoretical relationships and software analyses. More precise identification of this type of foundation behavior can be very difficult due to several influential parameters and interaction of set behavior, and it will be done by doing time-consuming computer analyses or costly full-scale physical modeling. In the meantime, the technique of artificial neural networks can be used to achieve this goal with minimum time consumption, in which data from physical and numerical modeling can be used for network learning. One of the advantages of this method is the speed and simplicity of using it. In this paper, a model is presented based on multi-layer perceptron artificial neural network. In this model pile diameter, pile length, and pile spacing is considered as an input parameter that can be used to estimate maximum settlement, maximum differential settlement, and maximum raft moment. By this model, we can create an extensive domain of results for optimum system selection in the desired piled raft foundation. Results of neural network indicate its proper ability in identifying the piled raft behavior. The presented procedure provides an interesting solution and economically enhancing the design of the piled raft foundation system. This innovative design method reduces the time spent on software analyses.

Development of New Modality Municipal Public Transportation for Guangzhou—Group Rapid Transit System

Ru-jiang Zhao,Wung Hee Moh

《工程管理前沿（英文）》 2015年第2卷第4期页码 378-390 doi: 10.15302/J-FEM-2015061

摘要： As one of the primary business centers of China, Guangzhou has been undergoing rapid growth and expansion. Over the past decade, the Guangzhou Municipality Government has significantly upgraded its transport infrastructure, especially with the highly beneficial expansion of its Subway Mass Rapid Transit (MRT) system. Positive steps have also been taken to continue planning the construction of new roads, a Bus Rapid Transit (BRT) system and other transportation facilities. Further administrative and regulatory measures have also been implemented to control the situation, such as the banning of motorcycles from the central city area and the limitation of new automobile registrations. However, Guangzhou continues to face serious challenges of traffic congestion in and around the city center owing to further intensification of its population with economic growth. The need to ease Guangzhou’s stretched public transportation resources, and at the same time to support the realization of its “Eastward Advance” strategy, presents a unique challenge and opportunity to develop an advanced high-efficiency public transportation modality for Guangzhou, viz. the Group Rapid Transit (GRT) involving the use of automation-guided (driverless) smart-vehicles. This paper outlines the PRT/GRT (PRT: Personal Rapid Transit) smart-vehicle modality and also puts forth a proposal of Guangzhou’s first GRT route as the city’s first dedicated transportation link to the scenic landscape of the Eastern Tourism Zone. This GRT route will help in diffusing the city’s traffic congestion as well as support the effectuation of Guangzhou’s “Eastern Expansion” strategy, supplementing the ongoing expansion of the Guangzhou Municipality’s subway MRT networks.
