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