Prestressed segmental precast (PC) piers, with insufficient energy dissipation capacity, are seldomly adopted on bridges in seismic areas. To improve the performance of PC this study proposes a functional separation isolation device (FSID), serving as supplementary replaceable device. Full-scale field load tests real-world pier were carried out to qualify type piers. Based results and numerical...

The development of the construction world in terms innovation has become one methods supporting success to gain advantages cost and time, which is outer wall can generally categorize into cast-in-situ precast methods. (1) Comparison implementing kumkang materials, concrete facades, curtain facades. method 24% cheaper than method, 87% 52% method. Sorted from cheapest most expensive are facades.&...

For the last decades, the design floods of numerous embankment reservoirs were re-evaluated, and the revised spillway outflows are typically larger than those used in the original designs. As a result, a number of overtopping protection systems were developed for embankments and earthfill dams, with applications encompassing river dykes, coastal barriers for storm surge and tsunami protections....

The paper presents results from three large scale experiments on seven reinforced concrete panels obtained during an extensive experimental program. This was aimed at possible application of cement reduced (fly ash replaced) concrete in the production of precast segmental linings for tunnels created by a tunnel boring machine (TBM). In particular, this paper is focused on the comparison of fire...
