摘要：A systemically study on the new space strucutre steel-concrete composite ribbed shell is made, which is loaded by stepped load. The ultimate bearing capacity and failure modes are investigated bsed on the characteristic response indicators. In the foundation of large number of parameters analysis, the influence of the span ratio, span, boundary condtitons and initial imperfection on the ultimate bearing capacity and istable bynamic failure are discussed in details. All the results will provide mass of data to the investigation of failure mechanism and the property under complex dynamical loads
