文中通过五根试验T梁研究了CFRP加固梁在不同锚固方式下的的承载力、挠度、裂缝宽度、破坏形态等特性,比较了原梁与各个加固梁之间的试验参数,分析了参数差异的原因.建立缠绕锚固CFRP加固梁的非线性有限元模型,提出了CFRP加固梁缠绕锚固的承载力建议计算公式.研究表明采用碳纤维缠绕端箍板的锚固方式加固效果良好,对实际工程加固具有很好的现实意义. 相似文献

主要介绍钢筋混凝土受扭构件采用粘钢加固的一些理论分析与试验结果。从理论上分析了粘钢加固能够提高钢筋混凝土构件的受扭承载能力,并推导了受扭构件粘钢加固后的极限承载力的计算公式。在理论分析的基础上利用ANSYS有限元程序,以数值分析模拟了加固的受力、破坏全过程,并介绍了受扭构件的结构试验结果。综合理论分析、数值计算、结构试验可以得出粘钢加固能有效地提高构件的受扭极限承载能力的结论,推导了相应的计算公式。 相似文献

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues. 相似文献
