The seismic hydrodynamic pressures observed at 4/7/8 submerged depths from two level inputs of ground motions and two direction combinations show that the representative values per unit area increase with submerged depth obviously, the increasing rate is generally faster than those by the two classical assumptions at shallow depth, but slower at deep depth.","PeriodicalId":30320,"journal":{"name":"Constructii Journal of Civil Engineering Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83985016","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}

Thus, to control such distress it is necessary to understand the mechanics behind such crack initiation and propagation and to find the fracture parameters to choose best mixture to resist the failure. There are various methods to understand the fracture properties of the bituminous concrete (BC) mix. This paper describes the semi-circular bending test for BC mix, which was designed to be very effective, and user friendly. This method is adopted because it simulates the field conditions and its availability. Semi-circular samples of forty-eight were prepared out of which half was made of unmodified bitumen and the rest were made of plastic modified bitumen. These all samples were then tested at different loading rates and value of load at each deflection is measured. Two fracture parameters like fracture energy and stress intensity factor are evaluated. The plastic modified bituminous concrete shows that the value of energy is increased 2 to 3 times than the unmodified bituminous concrete at intermediate temperature. Hence, plastic modified bituminous concrete has the greater cracking resistance potential.","PeriodicalId":30320,"journal":{"name":"Constructii Journal of Civil Engineering Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88059500","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 major considered factors included school area, number of students, number of teachers, number of classrooms, gender of students, education level (elementary, secondary), and school ownership (public, private). A total of 118 different types of schools were surveyed from different areas in Irbid City. The required field data were collected on regular weekdays by field surveys and manual counting for the total number of parked vehicles and the variation during the schools working hours, while schools descriptive information’s were obtained from the directorate of education in Irbid city. Peak demand models for different types of schools were developed using multiple linear regression analysis by SPSS software. The results of the study showed that the main affecting factors on school parking demand include the total number of students, classrooms, and teachers. However, more focus was given to the number of students due to collinearity among these main independent variables and to be consistent with the international practice.","PeriodicalId":30320,"journal":{"name":"Constructii Journal of Civil Engineering Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82961316","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 following year, an international competition was announced for individual buildings of the campus. What does the realization of this plan looks like? Was it possible to build this campus quite near the center of Vienna? Where does this incredible number of students fit? How do they live and study there? Is it possible for a total of six teams of architects from around the world to design a campus of the future together? What is the transport solution for such a complex? How to study and how to live in the space created like this? What is the public space of this campus about?

As a result, administrators are dealing with the effects of traffic congestion, under-utilized public transit systems, limited funds, and increased problems with environmental impacts. Even if still emerging, many regard mobility as a Service (MaaS) to be an approach that could help authorities develop transport services and reduce some of the problems facing the system.
