Taking a public building as an example,this paper introduced the construction technology of standing seam Al-Mg-Mn alloy metal roof system,elaborated from construction installation process,roof panel construction materials processing technology,control key points and other aspects,can provide reference for similar roof engineering.

Taking the plastic runways and training ground of the first-storey track and field training of B Stadium for Training Base of Shanxi Sports Center as the example,the paper introduces the construction craft process for the indoor EPDM(Ethylene-Propylene-Diene Monomer) plastic runway and its construction controlling points,so as to accumulate some precious experience and provide some reference for similar projects.

This paper introduced the application of reinforcement truss floor support plate in a re-covering steel structure engineering,separately elaborated the composition,characteristics,construction technology and operation key points of reinforcement truss floor support plate,and through the comparison to opening shaped pressure steel plate,pointed out that the reinforcement truss floor support plate was helpful for accelerating speed,reducing cost,the integrated benefit was distinct.

Analysis of tower crane's moment limiters'detection method and process.On the tower crane torque limit detection method and process analysis.According to the current standard,put the perfect testing methods and real scientific test data to record.

Comparisons were made on the results of these single-pile composite foundation.This paper calculated the reduction coefficient "β" of the soil among piles by the formula from the Technical code for ground treatment of buildings that is used for calculating the bearing capacity of the composite foundation.Considering of the different ground soil condition in Yingkou district,the value standard of reduction coefficient "β" of the soil among piles for the powder-spray pile composite foundation has been presented.And the results could be the reference for designing the composite foundation in this district.

To ANSYS the multi-flue chimney of a power plant,a three-dimension model is built up by using software ANSYS.The natural frequencies and modes of vibration are obtained by performing vibration mode analysis.Moreover,two types of seismic calculation methods,that is,response spectrum analysis and time-history analysis are used in this paper.Some results such as the displacement,shear,moment of the structure are obtained.Some observations about the results are presented.
