Durability damage of reinforced concrete bridges in an offshore environment often occurs varying degrees with the extension service life. Meanwhile, statistical data on earthquake show that most main earthquakes are accompanied by strong aftershocks, and seismic response under shock aftershock is different. To analyze effects sequence durability performance bridges, this study establishes a nonlinear dynamic analysis model bridge continuous rigid-frame girder based OpenSEES platform....
Purpose For coastal bridges, the ability to recover traffic functions after earthquake has crucial implications for post-disaster reconstruction, which makes resilience become a significant index evaluate seismic behavior. However, deterioration of material is particularly prominent in bridge, causes degradation As far, research studies on bridges considering multiple factors and different disaster prevention capability are scarce. further evaluating behavior bridge long-term context,...
Multivalency represents an appealing option to modulate selectivity in enzyme inhibition and transform moderate glycosidase inhibitors into highly potent ones. The rational design of multivalent is however challenging because global affinity enhancement relies on several interconnected local mechanistic events, whose relative impact unknown. So far, the largest effects ever reported for a non-polymeric inhibitor have been obtained with cyclopeptoid-based Jack bean α-mannosidase (JBα-man)....
An Engineered Cementitious Composites (ECC)-Reinforced Concrete (RC) composite pier with high-strength steel bars was developed to address various deterioration concerns in bridges, such as reinforcement bar corrosion, decreased concrete strength, and inadequate seismic performance of RC piers. This paper focuses on the bridge ECC-RC piers bars. The nonlinear finite element models bridges common are established using OpenSees. Considering effect chloride erosion during service damage repair...
Naturally occurring pyrazofurin has a wide range of antitumor and antiviral activities. Aryl pyrazole C ‐nucleoside analogs have been synthesized in good to excellent yields by one‐pot coupling reaction sugar alkynes, acid chlorides, hydrazine hydrate at room temp. The method is general, mild, efficient, 62 examples are given. alkynes include acyclic sugars, furanosides, pyranosides, with free hydroxyl groups, various protecting such as benzyl methyl sensitive isopropylidene sterically bulky...
For offshore bridges, the most prominent problem in whole life cycle is that it an earthquake prone zone and corrosion environment at same time. A nonlinear dynamic analysis model set up for multispan continuous rigid frame bridge based on OpenSEES platform. The fragility surface of pier, bearing, platform, system are established by selecting a reasonable damage constitutive material durability index studies to time‐varying seismic components environment. results show will lead constant...
In recent years, assembled bridges have become widely utilized in bridge construction, raising concerns about durability-related diseases over time. These issues significantly impact the fatigue life of bridges, necessitating an in-depth exploration their performance. While existing research primarily concentrates on transverse connection multiple longitudinal beams, there is a notable dearth studies precast segmental bridges. This paper addresses this gap by establishing benchmark finite...
The bond‐slip effect has a great influence on the seismic performance of reinforced concrete structures and ignoring it will overestimate structures. Based low‐cyclic reversed loading experiment column, this paper uses OpenSees to establish nonlinear finite element model considering verify its correctness. In paper, multispan continuous girder bridge with varying pier heights is taken as an example. Considering behavior steel bars, refined based platform established do numerical simulation...

To ensure water quality safety, construction method beam and then arch was adopted, which tube ribs were constructed by vertical rotation. monitoring rotation conducted numerical analysis clarify strength stability tower ribs, evaluate safety support local...
AbstractThe wind resistance of transmission towers is not only affected by load, but also service environment. This study uses the world's second Ultra High Voltage Direct Current project – Xinjiang ±800 kV Tianzhong Line UHV DC to develop a fragility analysis method for in saline soil under loads investigate change long-term It develops tower-line-foundation (3 T-2L-F) system model considering soil-structure interaction. In addition, this research addresses durability damage tower using...
A multispan continuous 3D bridge model is established on the basis of OpenSees platform, and 160 mainshock‐aftershock (MA) sequences are constructed in accordance with site to study their influence seismic vulnerability bridges.
