特殊场地与结构限制条件下外挂塔式起重机的研究与应用

国锐广场A,B座办公楼受业主经营要求影响,起重机安装位置受到极大的限制,同时,核心筒尺寸较小,筒内同时安装两台塔式起重机无法正常运行;采用外挂塔式起重机安装在核心筒墙体上是最合理的方案,在北京实施尚属首例,保证核心筒结构安全性不受影响,同时保证起重机在安装及爬升时的操作人员安全是本项目研究的重点。

无人货驳的坐底式打捞起重工程船改造设计

为有效实施针对浅水礁区搁浅失事船舶的海难打捞作业,将1艘无人货驳改造为坐底式打捞起重工程船,基于合理的坐底稳性和强度评估,通过船体布置优化设计、船体结构加强及相关设备系统的配置,结合结构应力监测系统的设置,使得改造后的船舶能安全可靠地进行坐底打捞起重作业。

基于半潜驳的坐底式风电安装船改造设计及应用

为解决现有海上风电安装设备的不足,将原"三航工5"半潜驳改造为坐底式风电安装船,并研制一套船体结构应力监测系统,对国内某海上风场砂性地质条件引起的冲刷和船底掏空进行监控。实际工程应用表明,改造后的船舶在安全性和工效上满足坐底安装风机的要求。

浅谈既有建筑隔震加固和隔震支座托换施工中的质量控制

本文结合泰州市口岸中心小学异地改扩建工程—教学楼既有建筑结构加固和基础部位隔震支座的施工,针对新增隔震橡胶支座部位原结构梁柱节点上部结构荷载不同,角柱、边柱、中柱的受力状态不同,在隔震支座的施工顺序的选择、顶升设备的选择、顶升荷载大小的控制、隔震支座施工前后对结构变形监测等施工中的重点和难点提出了相应的质量控制要点。

Operational Methods for Ships in Waves From Perspectives of Structure Health and Maneuvering Convenience

Based on the stress-strain data collected by a CSSMAS （container ship structure monitoring and analyzing system） onboard a container vessel, stress-strain responses of the ship＇s structure in high wave were analyzed and illustrated for the identification of reasonable safe course sections. Besides the ship＇s structure safety, the maneuvering convenience is also deemed as a main concern which influences the safety of vessels in heavy waves. In order to develop a comprehensive guidance in adverse weather condition, the basic requirements on maneuvering convenience for vessels in storm were further discussed. In combination of the two requirements, namely structure health and maneuvering convenience, a proposed operational method was thus developed, which was an amendment to the traditional navigational method for ship in extreme weather. At the end of this paper, an example of optimal course planning in bad weather was illustrated by using the operational method proposed.
