Parameters Study On Durability Of Substation Structure Of Multi-Tower Suspension Bridge, Qin Xiao, Pan Ji, Xiao Rucheng

Journal of China & Foreign Highway

Substation structures are important components of the bridge structure, and their durability will affect the service life of the overall bridge structure. Since the overall structure of a multi-tower suspension bridge is more flexible with larger deformation, and the cumulative displacement at the substation structure is also larger, the durability problem of the substation structure is more prominent under multi-tower suspension bridges. To qualitatively analyze the influence of the structural parameters of the bridge structure (including tower-beam connection and cable-beam connection methods) on the durability of the substation structure, this paper built a finite element model of a four-tower suspension …

Evaluating The Permeability Of Porous Aggregate Concrete Using Electrical Resistivity-Based Measurements, Ariel Miguel Mendez Aragoncillo

Theses and Dissertations

Recycled concrete aggregates (RCA) and lightweight aggregates (LWA) are popular alternative aggregates for concrete. However, due to their highly porous structure, concrete with RCA and LWA shows a different microstructure and higher permeability than conventional concrete. Thus, the existing relationships used to evaluate the permeability and, consequently, the durability of concrete are not applicable in concretes with RCA and LWA. This research examined the permeation properties of recycled aggregate concrete (RAC) and lightweight aggregate concrete (LWAC). The relationships between electrical resistivity-based measurements in RAC and LWAC and their permeation properties were determined and compared to that of normal weight aggregate …
