In this paper, using the Sap2000 analysis software, established the analysis model of high-rise reinforced concrete filled steel tube frame structure, in allusion to the damping effect in different number, different layout and different spectral characteristics, and carried out the optimization of damping wall configuration scheme. According the calculations, comparing the influence of seismic performance between the original structure and after optimization of concrete filled steel tube structure in the condition of earthquake, the results showed that the viscous damping walls in the structure damping control effect is obvious.
Combining the site relocation project of New Era Cement Co. Ltd, the early temperature and strain monitoring and numerical simulation are done on the cement vertical mills mass concrete equipment foundation sizing 15.6m×15.6m×5m, thus, the early trends and rules of mass concrete about temperature and strain are analyzed. Prevent temperature cracks due to temperature strain in mass concrete, therefore, ensure the construction quality of mass concrete.
A fiber filter based on side-polished method is proposed. Using Fresnel's law explains how it works. The filter output the following wavelengths, 1514.9 nm, 1532.9 nm, 1551.7 nm and 1569.0 nm and the isolation between channels up to 18 dB.
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.
