To study the seismic performance of the box-plate steel structure system, two three-storey single box-plate steel structure space stress-bearing unit test pieces have been designed and fabricated according to the 1 : 3 reduced scale. In addition, the quasi-static loading test has been performed on the test pieces where the destruction process, destroy mode, bearing capacity, hysteretic behavior, etc., have been studied and the impact of reinforcing measures with a corner or not on the seismic performance of test pieces has been mainly analyzed. The test results show that the destruction of the box-plate steel structure modular unit under the low cyclic loading effect starts with corner buckling and ends with corner wallboard tear. The test piece has excellent bearing capacity and energy dissipation; the corner reinforcing structure measure also has enhanced the seismic performance of the modular unit. Based on the test, we have taken finite element numerical simulation to the test pieces, compared the analysis result of the test with the finite element, and verified the effectiveness of the finite element analysis method. This paper designs four groups of 64 finite element model test pieces and discusses the influence law of the height-thickness ratio of the wallboard, flexibility coefficient of corner reinforcing structure rib, and axial compression ratio to the seismic performance of the modular unit. The results show that the bearing capacity of the test piece is decreased with the increase of axial compression ratio under the premise that the wallboard height-thickness ratio and flexibility coefficient of the corner reinforcing structure rib are certain. Based on the above analysis results, we have put forward the lateral force resistance calculation model of the reinforcing structure modular unit with or without corner.
Liaoning province is abundant in tourism resources and has become an essential destination and generating place of Northeastern Asia. It has featured tourism itineraries including six world cultural heritages. The province is positively exploring the way of coupling development of tourism industry and modern service industry and has made certain achievement. Based on Diamond Model propounded by American scholar Baud, this research paper analyzes the various factors existing in the process of coupling development of tourism industry and modern service industry in Liaoning, concludes its competitiveness, and proposes the beneficial suggestions.
Tourism is one of the pillar industries in Liaoning Province, and plays an essential role in domestic economy. This research paper analyzes the six basic elements and existing problems in the development of Liaoning tourism based on American famous scholar Michael Porter’s Diamond Model. Then it proposes the six countermeasures promoting the competitiveness of Liaoning tourism.
Owing to the increasing complexity in the construction safety management, integrating experts' knowledge and experiences to make appropriate decisions is a commonly used method. Decision making problem is the process of finding the best option from all of the feasible alternatives. In this paper, non-structural fuzzy decision support system (NSFDSS) was applied in the prioritization of evaluation criteria based on some additional advantages identified. Finally, a numerical example which was drawn from the national standard in China is used to illustrate the procedure of the proposed approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
