This paper presents a novel progressive mesh model based on collapse tree, which can accomplish the disordered expansions and collapses of the simplified mesh and is able to restore the mesh just in a specific area. With arbitrary collapse and expansion, we design an edge collapse algorithm for mesh optimization. Its summary process can be described as follows: generating a series of new simpli...

Abstract To investigate the effect of nano carbon-fiber-reinforced polymer (nano CFRP) on retrofitting reinforced concrete (RC) structures, this article presented progressive collapse performance two half-scale four-bay RC frames including one control specimen S1 and S2 with CFRP beam ends. The was discussed by comparing crack patterns, failure mode, load–displacement curves, horizontal displac...
