The mainshock (MS) is often accompanied by a number of aftershocks (AS). existence AS may cause the seismic demand to be greater than MS. In order better evaluate impact AS, this paper takes RC columns as research object and performs incremental dynamic analysis (IDA) on actual recorded mainshock-aftershocks (MS-AS). Park–Ang model damage index are used quantify effect MS respectively. fragilit...

This paper presents a procedure for rehabilitating plastic hinges with damaged/fractured weldable longitudinal rebars in severely damaged reinforced concrete (RC) bridge columns and possible improvements regarding connection protection hinge development. Damaged/fractured are replaced new rebar segments, the basis of this approach involves connecting intermediate machined parts to original by w...

The study was designed to investigate the effects of dietary Selenium-enriched radish sprouts (Se-RS), Vitamin E (Vit E), and Rhodobacter capsulatus (RC) on immunity, cholesterol concentration, and fatty acid composition in broiler meat. A total of 100 two-week-old male broiler chicks were randomly assigned into five dietary groups: I) Control; II) Se-RS (5 μg/kg Se-RS); III) Se-RS+RC (5 μg/kg ...

Due to structural degradation, the performance of concrete bridges may degrade with time and result in catastrophic consequences. A novel approach is developed for evaluating time-variant reliability multi-girder considering effects load-carrying mechanism redundancy. By three failure modes at both component system levels, a new indicator proposed quantitatively load elastic distribution plasti...
