Research on Ultimate Bearing Capacity of Single-Layer Cylinder Latticed Shells Considering the Influence of P-δ Effect

Abstract:

The ultimate bearing capacity of the single-layer cylinder 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. The ultimate bearing capacity of the single-layer cylinder latticed shell structure was studied in detail by proposing a method of multi-element simulation, considering the member instability. The value of the ultimate bearing capacity decreased by 1.2% 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 tiny affected for the single-layer cylinder latticed shell structure with a small span and high rise-span ratio
