Innovative Application of Prefabs in Earthquake-Resistant Bridge Construction
Abstract: Abstract Pre-stressed concrete, widely known to be a prefabricated structure (Prefab in short) has long been accepted in statically loaded structures. Thus, we have seen the construction of pre-stressed concrete bridges, dams, pipelines, reservoirs and various structures including more recently atomic reactor pressure vessels. In recent years pre-stressed concrete has been specially used in seismic resistant structures. Just like any other new material, it will attract criticism and comment, sometimes …
