Creep deformation and failure under cyclic thermal loading

Nuclear Engineering and Design, 1989
Abstract The purpose of the present paper is to demonstrate how the results of limit load and shakedown analyses can be utilised in the prediction of the deformation characteristics and life of structures subjected to cyclic thermal loading. The structural response is described in terms of a material test conducted at a constant reference stress and ...

Wind load equivalence method and structural response analysis of large-span space steel structures [PDF]

Archives of Civil Engineering
In coastal areas, large-span space steel net trusses experience structural deformation due to strong winds. Currently, the application of equivalent static wind load to the structure does not consider the influence of local forces. The local uneven force
