Research on the Influence of the P-δ Effect to Ultimate Bearing Capacity of Single Layer Latticed Shell Structures

Abstract:

Article Preview

The ultimate bearing capacity of the single-layer latticed shell structure, calculated without considering the single-member instability(P-δ effect), was not consistent to the actual value of ultimate bearing capacity in practice. It was studied in detail that the ultimate bearing capacity of the single-layer latticed shell structure considering the member instability by proposing a method of multi-element simulation. The value of the ultimate bearing capacity decreased by 15.6% after considering the member instability taking a single-layer latticed shell structure with a 40m span as example. The analysis results show that the value of ultimate bearing capacity is significantly affected for the single-layer latticed shell structure with a small span and high rise-span ratio
