Large-tonnage cranes steel plant in the application of light
Beam support. In the light steel plant, due to weight of the roof system is very small, so in general the earthquake it can not consider the impact, so the columns supporting the roof support and the main wind load and play a passing role to ensure roof integrity. The forces and the factories of its crane tonnage is not much in the relationship, therefore I believe that the columns supporting the roof support and the layout should be \load calculation bar (usually in the corresponding position instead of the roof purlins), if necessary, can be set to double purlin or other strengthening measures. However, different from the next column support, large-tonnage cranes in the plant, due to relatively large crane longitudinal braking force,[link widoczny dla zalogowanych], the force under the supporting columns are larger, so I think that should be \89) in the relevant regulations. At this point then purlin struts can not meet the requirements as shall be specially set up bar. At the same time frame as much as welded H section steel column, the weak plane stiffness, combined with the opening section, it is very light steel anti-reverse calculation of the performance of several Li Yongjun --- one by one {1, 'the following example, 1 second Abstract In this paper, (3ms ~ calculated frame, steel frame tips and precautions. discussed the web computing, slenderness ratio of female co-Beirut-lin .1 {I 【l,. c structure (. 3 ∞ D3S ~ School development structure. It has the advantage: can be adapted to a large span and large is the development of Ningbo in the tin phase Tongji University 'l area, a large column grid requirements of the joint plant; j-housing construction speed design software. The software can be used for steel frame,[link widoczny dla zalogowanych], door I just fast, effective early; structure, lighter weight, can reduce the investment base frame, independent tower, steel roof trusses and crane beams and other steel】 information. In view of these advantages, most of the construction of the plant owners design. can be used for plane analysis, can also be used for spatial boat t willing to use the halo of light steel structure, our hospital in recent years, analysis of plant design. from the use of point of view, academic analysis of the software than \beyond the concrete structure of the trend. pen the actual design of the project. the Court used the steel frame and doors are fortunate enough to complete the Science Park in Tianjin Yat-sen (door frame) and frame, door frame as a quick way to generate , where the ring Lucky New Materials Co., Ltd. (steel frame) does not talk about the two workers, mainly to discuss the calculation of steel frames. process. in the design process through the use of deep research and frequent D3s \one bound by the provisions of a \. basic operation instructions can be found here, and only the \only create columns and the main beam, second beam of the weak. but in the plant, the crane beam center line and column center line more than a bias. This crane longitudinal braking force generated in the column to reverse the effect on the structure of disadvantage. Therefore,[link widoczny dla zalogowanych], in engineering , we passed under the crane beam flange and column flange lateral angle between the additional support, while the location of the column web response tied additional rigid approach to eliminate the longitudinal braking force on the cable car to reverse the effect of column, this practice is necessary. Finally,[link widoczny dla zalogowanych], in the handling of each node. in a large-tonnage cranes plant,[link widoczny dla zalogowanych], due to structure weight is smaller than the level of force as the role of horizontal crane, a large column base moment. This matter on the basis of design or the design of the column foot. are at risk. In order to maximize the role of columns at the end of the embedded solid, reducing the actual displacement and calculated displacement of the gap between the column foot light steel structure proposed approach, by weight steel structure column foot treatment. such as the use of not less than 30nan thick floor; set up columns in the column foot boots, so as to try to ensure that the work performance of column base plate plane. In addition, the role of the large cranes, require a higher node on the bracket, so For the corbels at the (often also the junction of the upper and lower column), should shoulder heavy steel beam on the column at the approach to design. particularly should be noted that, due to the light steel structure houses to encourage the portal frame beams with thin webs, in order to save steel, but in the large-tonnage cranes plant, due to the larger internal force, often require a larger cross-section and thick column flange plate, requiring checking the web and flange beam connection weld strength. In short, there are large-tonnage cranes steel plant and general light house on the internal force is not essentially different. As long as we can handle properly. will try to use steel in its place can fully play its role It is certainly not only meet the security needs, but also to meet economic needs.
