    Structural Analysis and Redesign of Qalqilya commercial center under static and dynamic loads
    (2023) Ihab Nazzal
    This graduation project is the structural analysis and design of The Qalqilya commercial center in the city of Qalqilya in Palestine. The building is consisting of 6 floors with total area equal to 5186 m2. It consists of several facilities such as parking, offices, stores and residential apartments. Starting with studying the soil, the bearing capacity of the site is 350 KN/m2 . The analysis and design of the project was performed on gravity loads (dead, superimposed dead and live) will be studied in graduation project 1 and all loads including seismic loads will be studied in graduation project 2. Also, after studying the geometry and dimensions of the architectural drawings, initial dimensions of horizontal structural elements were calculated taking in consideration the predicted deflections, such that two- way solid slabs of 20 cm thickness are used. one beam sections of 50cm×45 cm was used. Initial dimensions of columns and walls were selected based on the probable axial loads applied. A three-dimensional model was built in ETABS 16.2.1. Loads, load combinations, materials, members, and stiffness properties are all modeled in the program. Before using the model, it was verified for analysis using compatibility, equilibrium, and stress strain checks. The proposed initial dimensions were checked taking in consideration deflections and axial and shear capacities of structural members. Before acceptance of design results from the program, they were undergoing to hand verification processes, such that one beam, one column, and one slab were designed manually, and they were compared result by ETABS. All results were within acceptable range of error.

    Foundation Design for a multi-story residential Building Considering Seismic Loads
    (2023) Mezar Saleh Idily; Monther Moamr Rawajbeh; Mohammad Jalal Sultan
    Foundation is the part of the building that lies below the ground level (the lower part of the structure) and transfers the structural loads to the supporting soil or rock. The main function of the foundation is to safely transfer highly concentrated column or wall reactions to the ground without causing soil failure or unsafe differential settlement of the supported structure. In fact, we believe that any structure will be and will remain safe as long as there is a safe path for the loads, in fact the structural elements such as columns, beams, slabs and finally foundations are mainly responsible for the transmission of loads in series on the ground. However, we can judge that foundations are the most important elements of any structure, and without foundations the structure would not rise above the ground. Foundation design includes a site inspection program to create the most appropriate type of foundation for a given structure that is affected by many factors such as: • Soil bearing capacity onsite. • The geological condition of the soil at the site. • Depth of foundation for adjacent buildings. • The load of the structure to be designed. • Other factors related to the expected stability of the site's soil.

    The interruption of financial support and its impact on construction sector and infrastructure in Palestine
    (2023) Basil Amjad Aydi; Oday Esam Kahla; Mahmoud Waleed Dwikat
    The construction sector in Palestine faced a remarkable decline in the previous period This decline is due to several reasons, the most important of which is the fact that Palestine is one of the developing countries that relies mainly in many large construction projects and infrastructure on financial assistance provided by donor countries. During the period 2017-2022, some donor countries cut or reduced aid for Palestine. This study examines some of the indicators that were impacted during this time and calculates the level of their influence. These indicators were generated from a number of earlier studies that addressed different aspects of this issue, and some of the indications came from interviews with engineers and other experts in the sector. A questionnaire was created as part of the work procedure and sent to engineering firms and general contracting firms. There were two primary sections to the questionnaire. General inquiries about the respondent are in the first section. The second and most crucial section addressed the indicators and categorized them using the Likert scale. Following the dissemination of the questionnaire, a statistical analysis of the information gathered from the questionnaire was conducted. The accuracy and reliability of the responses gathered were confirmed. The second section of the questionnaire, which dealt with indicators grouped into seven primary axes, was the subject of the statistical analysis (workers, project time, financial problems, contractor, project, public service problems, equipment and materials). The analysis's findings were listed as being not affected, median affected, high affected, and very high. The workers' axis was the most impacted, with a very high-rate impact. The equipment axis had the lowest rate, on median. The indicators used in the research were high impacted by the entire analysis.

    Analysis And Design Foundation of AL Eyman Building-Jenin
    (2022) Mohammad Sameer Soqy; Mohammad Khalid Ateeq; Nour Al Deen Naser Omar
    9 Chapter one: Footing Design 1.1 Introduction In our graduation project one we use ETABs program to analysis of foundation loads. and now we will use CSI SAFE PROGRAM to design the footing: 1. SINGLE FOOTING 2. MAT FOOTING But before that we should description the building and the site where it is located: 1- The building is a residential building with 7 stories all of them is above the ground level (see figure 1.1) 2- The height of the building is 22.4 meters including 7 stories. 3- The area of the plan for each floor is 342 m2, the total area of whole structure 2254m2 4- The building is designed to be a residential building, where each floor contains two apartments. 5- Jenin is a city in the north west bank, (see figure 1.2) north of Jerusalem approximately 75KM with a population 70000, Jenin overlooks the Jordan Valley to the east and Marj Ibn Amer to the north.

    Updating of the Existing Regional Master Plan for Water Supply in Tubas
    (2022) Anas Ahmad Haj Mahmoud; Hamdan Essa Dababat; Sohib Rushdi Jayyuosi
    The aim of the project is to analyze the water network of Tubas joint water service and sanitation council and redesign the network to meet the requirements for the next 20 years (2022-2042), where it service Tubas, Aqaba, Tayasir, Tammun, Al'Aqaba,Khirbet 'Atuf and Ras al Far'a Which has a population of 46889 according to Palestinian Statistics Center (2017) . The methodology that will be adapted in our project can be summarized in the following: 1-Collect information and reliable data. 2-Assessing the future demand for water, as the increase in the population will increase the demand, and studying the water gap that the Tubas Water Council will suffer from. 3-Based on available supply, the project will estimate future water gap for the different planning years, 2027, 2032 and 2042. 4-Devlop the existing water sources to bridge the future water gap. 5-Develop a master plan for the next 20 years with a description of the different proposed interventions. In addition, the project will prioritize the different interventions and develop a cost estimate for the different plan components. The expected outcome from this project is a master plan for the next 20 years with description of the different proposed interventions.
