| dc.description.abstract | Deterioration of old buildings in urban areas due to outdated structural, geotechnical, and architectural designs calls for the need of renovation in order to reuse those buildings. Renovation is becoming an effective way to extend service life of aging buildings, which are emerging as a crucial factor effecting resident’s wellbeing. Through performing renovation structure’s service live is extended, the living condition of its residents is improved, sustainable design is implemented, as well as structural strength, architectural and geotechnical designs are improved. For this project, a Soviet Union 5-storey precast concrete panel building located in the downtown area of Astana is chosen for renovation. The renovation includes downwards and upwards extension of the structure, namely construction of 2-storey underground parking and additional 2 storeys on existing building. Due to increased gravity load from additional storeys, the existing structure’s walls, slabs and connections between them are going to be strengthened and the old foundation is planned to be replaced to support the load of the new 7-storey structure and 2-storey underground parking. The project scope includes architectural modification of the structure’s exterior design presented as a 3D model in SketchUp software. The architectural plan of existing building is presented in AutoCAD drawings. As the entire project is performed based on American codes and the existing structure is constructed based on Soviet Union codes, the consistency of the existing structure’s space use and occupancy is checked and verified to be in an agreement with American codes. The data on interior environment, ceiling and flooring of the existing structure is collected and described in architectural design section. The modifications, in addition to construction of the parking and 2 storeys, also include construction of elevators, the selection and design of which is also described in architectural design section. The structural design includes analysis of existing building’s structural elements, specifically their strength and ability to withstand additional loads from upward modification, and the procedure and results of strengthening details. In order to proceed in this, design loads, which include dead, live, snow and wind loads, were calculated. Then, 3D model was built in SAP2000 software, from which internal design loads for each wall, slab and connections were obtained. Additionally, the internal design loads of specific members for one vertical and one horizontal case were calculated manually. The values obtained from SAP2000 for these cases and manual calculations were compared and verified. In addition to this, lateral drift analysis and check under wind load was performed. Based on the data on existing building’s structural members, namely reinforcement detailing, the design strength of each wall is calculated and presented in the form of M-N interaction curve. Design strengths of walls and joints are also calculated. From this analysis of design load and design strength, it is ensured that strengthening is not required as the walls, slabs and joints are able to sustain additional loads from vertical extension. Structural detailing of all members are provided in AutoCAD drawings. The geotechnical design was initiated by collecting data on soil profile of the region where the building is located. Based on the load from the structure, parking columns, slabs, micropiles and micropile connections are designed. Due to foundation replacement and excavation, dewatering is performed. Excavation process is designed in Plaxis to determine the settlement and ensure that it is within allowable limit. Sheet piles are also designed in Plaxis, as well as new foundation. The project management section involves the scope of the project, risk assessment and mitigation plan, health and safety plan, waste management plan, cost and time estimations, and risk management. Additionally, detailed Work Breakdown Structure and scheduling are prepared. | en_US |
