    Analyzing and Re-Designing of Foundation System for Asal Building
    (2023) مصطفى الاعرج; اسيد ابو عسل; سماح مليطات; سجى ابو طالب; محمد عصيده
    This project is an analysis of the foundation system for residential and office buildings (Asal Building) and the redesign of its foundations in the (Al Basateen) area. The building is located in the Rafidia area behind the Rafidia Tower in the city of Nablus, and it consists of (12) floors and a surface area of 14,423 square meters. The main objective of this project is to redesign the foundations of the building on weak soils and then compare it to the current design. All the loads on the building were calculated, and the soil bearing capacity was known, and then the dimensions of the new bases were calculated and drawn on the AutoCAD program. And since it was found that the building bases have a great overlap and the appropriate type of bases Raft or Combined foundation and will design retaining wall and shear wall .

    Land side Design of Yasser Arafat International Airport
    (2023) حذيفه جمعه
    This project analyzes the demand for a Palestinian international airport in Rafah, Gaza, for the design of and a land side of the airport. At the outset, a brief background is given on the location and necessity of an international airport in Palestine. The data obtained from the official authorities in Palestine, Jordan, Saudi Arabia and the Israeli occupation state were presented. First, this data is analyzed to relate it to the need to find demand on the land side in Palestine for the year 2050 which consists of travelers from the West Bank and Gaza Strip, Muslim and Christian pilgrims visiting the Holy Land, and tourists. Second, rush hour passenger volume is converted to rush hour vehicle volume based on other airport experience. Next, the number of staff, long and short-haul parking spaces and the required number of public transportation vehicles are calculated by the practice applied at other airports. After analyzing the demand of Gaza International Airport, the design of each component of the ground facilities is implemented. This includes the redesign of part of Salah El Din Street and the design of the airport road and parking areas. Initially the configuration of the airport facilities is determined. This is followed by the establishment of cross-sectional dimensions according to the American Association of State Highway and Transportation Officials (AASHTO). Finally, the thickness of the pavement layers for each road is determined and road signs and markings are installed. Gaza International Airport will be implemented in 3 phases starting in 2027 and ending in 2050. Analysis of the airport's demand shows that the total number of passengers for 2050 is 5,691,391 passengers and 1,198 employees per shift working at the airport. On the other hand, the number of vehicles heading to the airport reached 721 vehicles per hour, and 701 vehicles departed the airport per hour. As for public transportation, there are 114 airport taxis, 6 buses (50 passengers) and 4 buses (>26 passengers), and the total number of parking spaces at the airport is 575 parking spaces, which includes 55 short-term parking spaces. 244 long-term parking spaces, 200 parking spaces for employees, 68 airport taxi parking spaces, and 8 airport bus parking spaces. However, the connection between the airport and the road system in Rafah will be through a circular road connected with the airport road with two lanes at a speed of 70 km/h. The final cost of the ground facilities for Gaza International Airport is 14,190,715 ₪.

    The effect of using pyrolyzed carbon black(PCB) derived from waste tires as a partial substitute for cement in concrete mixes
    (2023) عباده جناجره
    The production of cement and concrete mixes produce many harmful bi-products to the environment, therefore, researchers are looking to handle and eliminate such materials and direct their ways to green concrete. This research aims to investigate ability of using Pyrolyzed Carbon Black derived from waste tires as partial replacement of cement in concrete mixes. This step will facilitate another forward improvements of green concrete and elimination of harmful wastes. In this research, different mixes with different percentage of cement partial replacement will be mixed and tested for mechanical properties of fresh and hardened concrete. Experiments include slump test of fresh concrete, compressive and tensile test. Results will be evaluated in term of direct effect of this wastage material, and ability of using the final mixes for both; structural and nonstructural concrete element. Varied mixtures of different weight percentage ratios of PCB to cement (PCB/c); 0% (control sample), 2.5%, 5%, 7.5%, 10%, and 15% are taken into consideration when examining various concrete qualities. Commonly, predetermined ratios of PCB/c are combined with predetermined volumes of cement, water, sand, aggregate, and superplasticizer after being prepared in accordance with international preparation standards. After that, a variety of mechanical tests are run to look into improving the qualities. Slump, compressive strength, and tensile test are among them. Results show a noticeable decrease in the compressive strength for tested samples for 7 and 28 days; however; slump values also decreasing as the replacement rate increases however; slump values are still within standard limits for most of the mixes. In addition, tensile test results were good, but not as expected. The best results showed at 2.5% and 5% of pcb cement reblecment. At the end we can say that can be use the previous concrete mixes in construction purposes.

    The Effectiveness Of Green Features On Life Cycle Cost - Aqqaba Green School
    (2023) رؤى ذيب; ليلى ابو وعر; عبير برهم
    Could you recognize the massive environmental, health and losses that we might face as a result of the traditional construction? Green building is the key. Since building and construction sector occupies the first place as the largest contributor to pollution and natural resource consumption, “green buildings “were introduced as a high potential solution to improve the performance of the built environment in term of economic, health, and environmental aspects by using innovative techniques that will reduce energy and water consumption, reduce emissions, reduce waste as well as maintain a moderate temperature. This research focused on the green buildings in Palestine and their assessment mechanism, as well as difficulties and challenges Encountered. Later on, the economic and environmental aspects of the green building during its life cycle will be highlighted, which will have the greatest role in attracting and encouraging investors. Moreover, increasing people's knowledge of green buildings and their awareness of the urgent need to implement these buildings at the present time by posting a questionnaire on different social media websites which in turn assesses the extent of their knowledge of its importance. Later, the economic aspect will be studied by converting a traditional building to a green one as well as a feasibility studies will be done on both cases

    Analysis and design deep foundation for the national_ hospital street in nablus
    (2023) وعد سعيد; محمد رجب; مصعب دعباس; عبد الرحمن صبحا; مصعب مرعي
    Retaining structures include various types of structures among them the use of sheet pile walls and braced cuts. Sheet pile walls and braced cuts are generally used for retaining the sides of cuts made in earth, in water front structures, dams, cofferdams and other purposes. sheet piles and braced cuts have several advantages compares with other retaining structures especially when we have limited access in the are of construction. Our project consists of designing a proper retaining structure for an area in the center of Nablus city. This area has very limited accessibility and a very dense traffic. Therefore We decided to use either sheet pile walls or braced cuts system. Our project will be devoted to study and compare between these two options in the analysis and design. To achieve this goal we will study the site and its soil condition and problems.
