The paper presents a review of planning and implementation of the coastal zone management in Sri Lanka. It focuses on the approach to coastal zone management via regulation of development activities and environmental protection, second-generation and current initiatives, challenges and constraints.

Concrete strains, temperatures and joint movements were measured using vibrating-wire embedment strain gauges and thermistors, while ambient conditions were monitored to assess their effects. A reliable, accurate and easy-to-implement methodology, developed by instrumenting four types of floor slab (mesh-reinforced long strip, mesh-reinforced jointed large area pour, steel fibre-reinforced jointed large area pour and steel fibre-reinforced jointless large area pour) is described in detail, along with the further developments and modifications to the instrumentation. The methodology developed would be equally applicable to the early-life monitoring of other concrete structural elements.

The scheme demonstrates the incorporation of sustainability considerations through design, construction and commissioning. Seeking to reduce the amount of household waste sent to landfill sites, the provision of a high-quality facility for recycling will encourage increased sustainability awareness and participation within the community. As a means of delivering a quality scheme, the challenge of ensuring high durability in combination with aesthetic and environmental enhancement has been met with innovation. Use of polymer fibre reinforcement in the heavy-duty apron slabs provides high durability under aggressive service loads. Elsewhere, incorporation of subsurface skips facilitates spatial optimisation and allows significant noise attenuation with minimal visual impact. Where possible, materials won from the demolition of existing time-expired structures were incorporated in the new scheme or d...","PeriodicalId":429763,"journal":{"name":"Civil Engineering Innovation","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131733863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

People will better understand the resource implications as well as the direct costs of their lifestyles—and perhaps they will actually travel less. However, given the slow speed at which infrastructure systems adapt, the research concluded that civil engineers need to start planning now for the inevitable travel revolution.

The framework has a modular format and includes components for dealing with inspection, data collection and storage, deterioration modelling, structural assessment, economic appraisal of maintenance, repair and rehabilitation (MR&R) actions through whole-life costing, work programme optimisation methodologies and a number of reporting facilities. Of primary importance to the bridge management process is the assessment of structural adequacy. If assessments are unduly conservative, structures will be unnecessarily restricted or strengthened, whereas if the rules are lax, some structures may be left in service without having an appropriate margin of safety against failure. To address this issue a procedure for a reliability-based assessment approach is presented and it is shown how such an approach, when part of the above system, can provide bridge managers with an...","PeriodicalId":429763,"journal":{"name":"Civil Engineering Innovation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115626100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After initial processing, the results gave plausible vertical and lateral (sideways) displacements, but also described implausible longitudinal movements along the axis of the bridge. Digital signal processing techniques applied to the data are reported. Due to the satellite constellation in the UK, a large void exists from the zenith to the horizon in a northerly direction. This lack of GPS satellites results in poor satellite geometry in the north-south direction, and hence poor north-south precision, explaining the unsatisfactory element of the Millennium Bridge results. More importantly a technique to overcome the issues is described. Notwithstanding this, the lateral vibration frequencies obtained from the GPS data agree extremely well with those found in the modal surveys carried out by Arup, even when displacement amplitudes are small.","PeriodicalId":429763,"journal":{"name":"Civil Engineering Innovation","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134135508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The performance of the bays has been continually monitored since their construction and the measured plan-shape of each bay has been compared with the theoretical predictions. This has shown that there is good agreement between the crenular plan forms predicted by the mathematical models and the theoretical methods, which are founded on the log-spiral curve that has been shown to represent the crenular plan form of naturally formed bays.
