To study the seismic performance of box-plate steel structure system, two three-storey single space stress-bearing unit test pieces have been designed and fabricated according to 1 : 3 reduced scale. In addition, quasi-static loading has performed on where destruction process, destroy mode, bearing capacity, hysteretic behavior, etc., studied impact reinforcing measures with a corner or not mainly analyzed. The results show that modular under low cyclic effect starts buckling ends wallboard...

Owing to the increasing complexity in construction safety management, integrating experts' knowledge and experiences make appropriate decisions is a commonly used method. Decision making problem process of finding best option from all feasible alternatives. In this paper, non-structural fuzzy decision support system (NSFDSS) was applied prioritization evaluation criteria based on some additional advantages identified. Finally, numerical example which drawn national standard China illustrate...

Based on the theory of fatigue life prediction and by using local stress-strain method material S-N curve Q235 deduced empirical formula; was analyzed for key parts large-scale liner vibration screener means general finite element analysis software, ANSYS. Thereby, working conditions force bearing, reliability life-span can be judged. The study will provide a theoretical basis design , manufacture, installation screener.

The finite element models of the planar K-joint are established based on analysis software ANSYS. bracing members under action axial force and moment. Different rotational deformation values joint with different geometric parameters reached calculation analysis. Results show that value approximate linearly increased increasing load member. It also shows influence member diameter wall thickness is larger part greatly influenced by region.

As an advanced way of transport organization, container with dumping trailers should be considered as a kind low-carbon and energy-saving mode for the popularization Green logistics developing vigorously in our country. Since is implemented later China, its organizational simply between two points. Therefore radiation range often limited by selected business routes. result simple organization mode, efficiency drop-and-pull has been greatly limited. In order to solve problems above, this...

By the method of experiment and finite element, production, development regulation location plastic hinge widened beam flange connections were studied. The test results showed good agreement with FEM proved analysis reliable. specimens designed as base samples. choosing some different main references relating to section shape change connections, a series element which include eighteen direct arc connection welded side-plate derived from influence depth, length distance on distribution is...

Recently, safety accident emergency management of construction project is an important issue not only for investors and governments but also the companies that are in industry. Designing evaluating crucial same sector’s development. Proposed method based on fuzzy TOPSIS, which combined TOPSIS with triangular numbers both rating alternative weight criterion. The closeness coefficient under environment calculated by using concept positive-ideal solution negative-ideal solution. Then rankings...

Based on the experiments of four connections with widened beam flange section which included two arc and welded side-plate specimens one ordinary connection under cyclic loading, 3-D nonlinear finite element models were created by using ANSYS software to analyze mechanical properties these types connections, such as skeleton curve, ultimate load, ductility failure mode etc. The analytical results show good agreement those prove correct applicable. According experimental results, PI(PEEQ...
