The effects of form on the arch structural response for static loading and span-toheight ratios (L:h) ranging from 2 to 8 are presented using finite element solution provided by the GSA software. Results have shown that circular arches represent least optimal shape, exhibiting high combined stresses and bending moments, particularly for the L:h ratio of 2 (semi-circular arch). The optimum L:h ratio for a circular rib arch is between 4 and 6, but the stresses that develop in it are still higher than in parabolic or catenary arches. This is with regard to the pure arch behavior for L:h≤5. The minimum of the combined compressive stresses in parabolic and catenary arches are observed at L:h ratio between 2 and 4. The parabolic arch demonstrated lower structural action effects when the uniformly distributed load (UDL) is greater than the self-weight (SW). Overall, the findings demonstrate that the response of 2-pin arch forms to applied loading is critically dependent on the arch form and its shape governed by the L:h ratio.","PeriodicalId":356543,"journal":{"name":"Proceedings of the 7th International Conference on Modern Research in Civil Engineering, Architectural & Urban Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129157838","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}

This dependency on individual private cars is usually due to the absence of other convenient public transportation. Egyptian cities are facing several environmental pollution problems from the crowded roads with the increased number of private cars. This paper will highlight the harmful impact of private car dependency on the environment and the urban context. Then, it introduces different solution that can help in minimizing the car dependency problem in congested cities. Then it goes for an analysis of the city centre of Copenhagen, which is considered the model of how to transform a large city from car dependent to a friendlier city for cycling and walking. Benefiting from the analysed case study, some solutions could be introduced to the city centre of Alexandria to solve car dependency problem within the urban context of the old town (Safeya Zaghloul Street).","PeriodicalId":356543,"journal":{"name":"Proceedings of the 7th International Conference on Modern Research in Civil Engineering, Architectural & Urban Development","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116060380","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 article argues how a food market building in the old area of a city might work as a catalyst for a cultural-led urban regeneration. A food market stands more than 80 years not only supply food for neighbourhood, but also conveys much of community public memories. By making market a school/ community museum and retell the stories to children, the richness of local community histories turns into a positive energy to lead the urban regeneration matching the local needs, instead of sacrifice to developer’s interest only.","PeriodicalId":356543,"journal":{"name":"Proceedings of the 7th International Conference on Modern Research in Civil Engineering, Architectural & Urban Development","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121883663","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}
