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 […]

Microstructure and pore structure of polymer-cement composite joint sealants

Basic properties of pore structures Pore size distribution of the polymer-cement composite joint sealants is closely associated with their macro-mechanical properties21, and with such durability indicators as anti-permeability and corrosion resistance. Based on the MIP results, this section analyzes the basic pore structure properties of the joint sealants by using the differential curves for pore […]

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 […]
