Special Issue Information

Dear Colleagues,

Since 1903, when the first multi-story reinforced concrete building was built by pioneering techniques (the 16th-story Ingalls Building, in Cincinnati, Ohio), building codes for their design and construction have been developing (with the historical note that it is Leaning Tower of Nevyansk built in 1725 in the town of Nevyansk in Sverdlovsk Oblast, Russia the first building known to use reinforced concrete as a construction method). Earthquake risk represented special difficulties, but at the same time the biggest incentive for improving building codes. By inspecting the damage to buildings after earthquakes i.e. their earthquake performance (e.g. after the 1906 earthquake in San Francisco in California, USA, …, 1999 Kocaeli earthquake in Turkey, 2008 Wenchuan earthquake in China, etc.), their key weaknesses in design and construction were observed, if the buildings were built in compliance with building codes. Since the 1980s, when building codes could achieve medium protection of buildings against earthquakes (damage much greater than expected, however a good level of life-safety protection), a new way of thinking has been developing, the so-called performance-based seismic design (i.e. Appendix to the SEAOC 1999 Blue Book). This special issue is focused on such performance, thus to examine the problems and the relationship between the design and construction criteria and seismic hazard exposure, acceptable risk and seismic performance of reinforced concrete structures.

Owing to the advantages of accelerated construction, reduced traffic disturbance, and enhanced quality control, precast segmental two-column bents are extensively utilized in urban and highway bridges, particularly in areas of low-to-medium seismicity. However, the application of this technique in high-seismicity regions is limited owing to insufficient knowledge about the seismic performance of such precast bents. To address this, the present study investigates the seismic performance of precast segmental two-column bents, focusing on the connection of “grouted splice sleeves and grouted central tenon”, namely the proposed GSS-GCT connection. For this purpose, three large-scale two-column bent specimens were fabricated and subjected to quasi-static cyclic tests: one cast-in-place bent, one precast two-column bent with conventional grouted splice sleeves, and another with the GSS-GCT connection. The benefits of the GSS-GCT connection under high seismic activities were demonstrated regarding lateral load-carrying capacity, displacement ductility, energy dissipation capacity, and residual displacement. Moreover, five levels of damage states were qualitatively and quantitatively divided based on experimental observation, which can be evaluated with lateral displacements. Furthermore, seismic assessments of the two-column bents were obtained using the capacity spectrum method. The proposed GSS-GCT connection could significantly improve the seismic performance of precast segmental two-column bents under high-level earthquakes. Full article
