以某非对称双塔连体超高层结构为研究对象,选取与建筑所在场地相匹配的地震波作为激励,通过对结构进行非线性动力时程分析,研究混合消能减震连体结构在各烈度地震作用下的消能减震效果,探讨了屈曲约束支撑(buckling-restrained brace, BRB)与黏滞阻尼悬臂桁架的位置变化对结构抗震性能的影响,同时对结构进行了全面的抗震性能评估。研究结果表明:在连体结构中、上部的加强层中布设阻尼器时,结构具有更佳的减震效果;在不同水准地震作用下,BRB与黏滞阻尼悬臂桁架耗能阶段不同且具有不同的耗能效率,混合消能减震技术可以综合不同类型阻尼器的优势作用,使连体结构具有更全面的抗震性能。在控制变形方面,其能够降低连体结构的扭转效应和层间位移角;在构件耗能方面,其减轻了主体构件进入塑性的程度,降低了结构主要受力构件的应力水平。将为混合消能减震技术在连体超高层结构中的进一步研究和应用提供借鉴。

Effects of Maternal Death on Children Living in the sagnarigu Municipality

Open Journal of Obstetrics and Gynecology 2024年第3期14卷 334-347页

作者： David Z. Kolbila abdul-Razak Doat David s. Nigarim Wilfred Kwose sylvanus Kampo Department of Obstetrics and Gynecology School of Medicine University for Development Studies Tamale Ghana Department of Nursing School of Nursing and Midwifery C.

Tedam University of Technology and Applied Sciences Navrongo Ghana

introduction: The greatest effect of maternal mortality is renowned in children aged 2 - 5 months whose mothers had died. Children whose mothers died due to maternal complications were likely to record a higher mortality in infancy compared to children of surviving mothers. Motherless children mostly suffer a lot due to lack of day-to-day care, isolation, lack of motivation as well as economic cost associated with mother’s death. Thus, the purpose of this study was to ascertain the lives of children whose mothers passed away during childbirth at the sagnarigu Municipality. Methods: This quantitative cross-sectional study was carried out at the sagnarigu Municipal. The study recruited 297 respondents. To assess the effects of maternal death on the lives of children, families that experienced maternal death were assessed. The number of pregnancies experienced by the deceased woman, pregnancy-related complaints experienced, determinants of maternal death, number of children alive, and their standard of living were assessed with the aid of a structured ques.i.nnaire. Results: The data showed that negligence, illiteracy, poor road access, poverty, ignorance, delays.i. recognizing the problem, delays.i. making appropriate decisions, delays.i. the health facility, delays.i. giving the appropriate treatments, and traditional beliefs were some of the factors that led to maternal death in the sagnarigu Municipality. Conclusion: The study concluded that determinants of maternal death in the sagnarigu Municipal included the following;negligence, illiteracy, poverty, and delays.i. recognizing the problem. The study findings also demonstrated that the effects of maternal death on children are diverse and cut across different areas of a child’s life including livelihood sustenance, healthcare, education, and emotional and psychological development.
