Quantitative non-destructive evaluation of push-fit joints

Ultrasound, closed-circuit television (CCTV) and Panoramo^® are capable of inspecting drinking water pipes and joints of any pipe material. The three tools were tested for their accuracy and reproducibility for gap width sizing in double-socket push-fit joints. The tests were performed at laboratory scale (PVC pipes and joints) in the field (asbestos cement pipes and joints) and in three full-scale tests (PVC) inside pipes used to supply drinking water. In the laboratory tests both accuracy and reproducibility were evaluated. In the field and full-scale tests only reproducibility of the tools was tested. CCTV proved to be the most accurate and reproducible for the application. This straightforward approach is considered to be a surrogate measure for joint's condition.     

CCTV主楼悬臂部位塔式起重机运行安全监测

CCTV主楼悬臂施工阶段,对塔式起重机在移位安装至悬臂部位过程中和使用状态下进行高频次、高精度、多点位动态监测.监测内容为垂直度和支撑梁水平度,分别采用激光铅直仪和电子经纬仪.通过对各测点监测结果的对比分析,得出塔式起重机底座的不均匀沉降和塔身位移变形数据波动范围均不大,满足塔式起重机安全使用限值要求;另外,悬臂部位塔式起重机自重及吊运负荷状态下对结构产生的变形影响很小,说明其底座设计及加固措施合理、有效.

Digital Morphogenesis

Taking its inspiration from biology, digital morphogenesis operates through a logic of optimisation. Departing from the notion of architecture primarily as form-finding that privileges appearance, Neil Leach describes how morphogenesis places emphasis on ‘material performance’ and ‘processes over representation’.

The relevance of sewer deterioration modelling to support asset management strategies

Deterioration modelling can be a powerful tool to support utilities in planning efficient sewer rehabilitation strategies. However, the benefits of using deterioration models are still to be demonstrated to increase the confidence of utilities toward simulation results. This study aims at assessing the performance of a statistical deterioration model to estimate the current condition and predict the future deterioration of a sewer network. The prediction quality of the deterioration model GompitZ has been assessed using the extensive data-set of 35,826 inspections performed in the city of Braunschweig, Germany. The performance of the statistical model has been compared with the performance of a simple model based only on the condition of observed sewers. Results show that the statistical model performs much better than the simple model for simulating the deterioration of the network. The findings highlight the relevance of using modelling tools to simulate sewer deterioration and support strategic asset management.     

Arup Associates

A specialist architectural division of the wider Arup group, Arup Associates has a unique composition and ethos. In its studios, teams of architects, structural engineers, environmental engineers, urban designers and product designers work alongside each other on the design of buildings from a project's inception. It is an interdisciplinary approach that the practice pioneered in the 1960s, and which has been reinvigorated in the last few years by a new emphasis on ‘unified design’ – a radical wholeness in thinking and execution. Here, Jay Merrick talks to Arup Associates' principal Declan O'Carroll and considers his vision of an architecture capable of addressing complexity and sustaining humanity in the face of modernity.
