In this paper, the dynamic response under blast loading of the blast wall, shear wall and common wall is simulated by ANSYS LS-DYNA simulation software. By analyzing the overpressure peak and stress changes of wall under the blast loading, we can get different material properties of the wall against overpressure, and the simulation results obtained by simulation calculation will provide a reliable...
As main load-bearing member, Concreted Filled Steel Column (CFSC) has been widely used in buildings and bridge structures. Research on bearing capacity of CFSC, especially under temperature load, was carried out mainly on the basis of experiments. In this paper, inverse method of elastic theory is adopted to introduce Airy stress function for study on CFSC under axial pressure and temperature load...
The leakage of air-conditioning refrigerating system will reduce the operation efficiency and bring about serious atmosphere environment pollution. This article puts forward that the leak detection of air-conditioning refrigerating pipeline system by means of stress wave detecting, we set up the NDT system and use the LabVIEW graphical programming software which was popular currently to determine...
