Mechanical behavior and waterproof performance of longitudinal section of tunnel segment joint gasket

Waterproof model of sealing gasket for segment joint The waterproof form of the tunnel segment joint gasket selected in this study is the type of separate arrangement of inside and outside, that is, two rubber gaskets are arranged separately on the upper and lower sides of the segment joint section, and the lower side of […]

Experimental investigation of seismic performance of precast concrete shear walls with overlapping U-bar loop connections

According to the “Specification for Seismic Test of Buildings”44, definitions of relevant mechanical characteristics can be illustrated as follows. The cracking load (Fcr) and cracking displacement (Δcr) refer to the load and deformation at the onset of cracking, respectively. Referring to the corresponding parameters of steel bars shown in Table 3, the specimen was deemed to […]

How and Why Bridges Are Made to Move

Everyone talks about the weather, but it falls to civil engineers to actually do something about it. Weather and temperature affect everything we use, from car batteries to bridges. When temperature causes changes in structure, it’s referred to as thermal expansion or thermal contraction, and it’s a phenomenon. you have to carefully control for if […]
