To improve the seismic performance of prefabricated reinforced conventional concrete (PRC) beam‐column joints, fiber‐reinforced concrete (FRC) was used instead of concrete in the core zone of the joint in this article. The optimum volume contents of polyvinyl alcohol (PVA) fibers and steel fibers were first determined to be 0.3% and 1%, respectively, through the material properties tests. Then, four PRC beam‐column joint specimens using grouted sleeve connections and one cast‐in‐place reinforced concrete beam‐column joint specimen were designed considering the factors of PVA fibers, steel fibers, with or without stirrups. The test phenomena and failure mode of the five specimens under low‐cycle cyclic loads were obtained. Finally, the effects of PVA fibers, steel fibers, with or without stirrups on the seismic performance of specimens were analyzed and discussed. The test phenomena indicated that the failure mode of specimens was anchorage damage of steel bars. The prefabricated FRC specimens showed relatively little damage in the core zone of the joint. FRC had a significant improvement on the seismic performance of prefabricated beam‐column joints. The use of FRC in the core zone of the joint can reduce or even eliminate the use of stirrups.
Background
The aging of the population has made the health problems of the elderly increasingly prominent, and their health needs are increasing. Existing studies on health resource integration approaches are mostly incomplete in assessing the health service capacity from the perspective of the health service provider.
Objective
The unmet health needs of the elderly were sampled and analyzed from the perspective of health service demanders. To explore how to build an integrated medical organization structure to better meet the health needs of the elderly.
Methods
A whole-group sampling method was used to conduct a questionnaire survey of 1527 older adults in N district of H city, Zhejiang province, China, to cross-sectionally analyze their current status of unmet health needs.
Results
The survey and analysis found that the needs of the elderly in this community to obtain disease-related knowledge, rational exercise, a healthy diet, and access to health information were not met. There were more patients with chronic diseases, and the top three chronic disease prevalence rates were hypertension (40.2%), dyslipidemia (8.4), and diabetes (7%). Chronic disease co-morbidities accounted for 13.3%.
Conclusion
The relatively independently set up health service system at the present stage in China can no longer fully meet the health needs of the elderly, and the health service providers should provide integrated and continuous health services to meet the needs of whole-cycle health management. Therefore, we believe that effectively integrating various health service providers in the region and building an integrated health service organization with general practitioners as the core may be a solution to the current situation of unmet health needs of the elderly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
