    Strengthening of reinforced concrete beams by using frp
    (UMT.Lahore, 2019) UMER FAROOQ KHALID MIRZA; MOHSAN ALI KHAN; AHMED DAOOD KHAN
    Over the top exhaustion crumbling is experienced more often than not when auxiliary components Reinforced Concrete are exposed to loadings. That stresses the longing to fortify just as improve the exhaustion execution and broaden the weakness life of RC auxiliary segments especially shafts. Fiber-fortified polymer (FRP) has turned into a generally utilized method during the most recent couple of decades, fortifying of cement basic components by where high quality is required for conveying substantial loads or fixing is done because of weakness splitting, disappointment modes and additionally erosion. This paper surveys different parts of RC bars fortified with FRP. This subject has not been canvassed thoroughly in past investigations, while the innovation has been changed quickly in the ongoing past. It Highlights viewpoints, for example, surface planning, glue restoring, limited component (FE) reenactment, weariness execution just as the disappointment methods of RC bars retrofitted with FRP. This method wipes out or potentially diminishes the split development rate, defer introductory splitting, decrease the firmness rot with leftover avoidance and expand the weakness life of RC pillars. The best fortifying alternative for this situation is pre-focused on carbon fiber-strengthened polymer (CFRP). Remembering the way that the utilization of these fortifying strategies has been ruined for the most part because of absence of thorough structure arrangements, the accessible rules/particulars are looked into and the elements that need further examination are recognized. To improve the comprehension of the general components of shear fortifying procedures with remotely fortified FRP frameworks, proposals for further research exertion are separated and suggestions for an improved rule are presented.

    Design of underground parking garage
    (UMT.Lahore, 2019) Abdur Rehman; M.Saad Waseem; Muneeb Nisar
    Design of Underground Parking Garage The current parking situation in UMT is an outside plot. This plot is not paved with proper asphalt or any wearing course. When it rains, the parking area tends to get muddy because the surface of the plot consists of soil and brick ballast. This causes great difficulty for vehicles to maneuver. The parking garage plays an important role in mobility. As paring issue come from the public behavior itself. So, that’s why for the design of the underground parking garage. For this parking garage we shall utilize the playing field/ground of UMT, while preserving the ground surface for the playing purposes. So, it is very important for a structural engineer, one has to consider all the possible loadings and design of structural elements (beams & columns) as well as to save the cost to compete in the ever growing competent market.To analyze and design the underground parking structure and to check the feasibility of structure, appropriate manual calculation was carried out after finalizing the dimensions. A detailed analysis was carried out using the software STAAD Pro. The architectural drawings were done by using the software approach called Auto-CAD.

    Design of swimming pool for umt campus
    (UMT.Lahore, 2019) Abdul Moeed; Zubair Farooq; Muhammad Junaid
    Swimming is a great exercise, fun & recreational activity accessible for all. UMT is a big university but as no swimming pool. From civil engineering point of view, the structural design of the pool was designed. A typical swimming pool consist of a pool, circulation system, pumps, inlets, outlets, pipework, filtration and chemical treatment system. This design is planned to be carried out in three phases. The first phase of the design consisted of surveying the selected site and visiting different public swimming pools in Lahore to make an appropriate plan and to finalize the dimensions & aesthetic looks of the pool. Thesecond phase of the design consisted of geotechnical investigation of the selected site. Determine the soil conditions, soil type and its perimeters (cohesion, angle of internal friction, bearing capacity etc.) by conducting different test like Tri-Axial, SPT etc. The third phase of the design involved the structural design of footings and retaining walls for this purpose different structural analysis and design methods was used. To analyze and design the swimming pool structure and to check the feasible of structure, appropriate manual calculations was carried out after finalizing the dimensions

    Progressive collapse of a reinforced concrete frame structure
    (UMT.Lahore, 2019) Wajahat Mehdi; Mirza Sikandar Baig; Haziq Waheed
    Progressive collapse is the ultimate failure in an element of a structure due to spread of local failure from element to element throughout the structure. Progressive collapse analysis of a reinforced concrete frame structure was performed using commercial software ETABS v. 16. A five story building was selected and designed under gravity loads as per Pakistan Building Code (PBC). Analysis for progressive collapse were made under two damage cases; edge column damage and corner column damage according to General Services Administration (GSA) guidelines. Linear static analysis was carried out on Corner and Edge column damage cases under fully (100%) and partially (80%) damages scenario. The results include bending moment diagrams, demand to capacity ratios (DCR) and deflection at critical members in cases with 80% and fully damage consideration. Structural member having DCR value greater than 1.5 shows severe collapse potential according to GSA guidelines. It is concluded that edge column with longer bays is found critical in the event of progressive collapse because the bays with longer span experiences more damage as compared with smaller span bays. As a result of it collapse will occur in short period of time and there is upsurge possibility of loss of lives under such condition of structures. Based on this research, practicing engineer should assimilate the GSA guidelines for loading along with the other loads so that potential for progressive collapse may be lessen up to some extent.

    Rainfall runoff modelling for flood risk estimation in swat, kalam region
    (UMT.Lahore, 2019) Jehanzeb Raqeeb Rao; Rohan Saadat; Syed Asadullah Shabbir
    The problem of recurrent floods has been causing massive losses to lives and other properties and Kalam valley is no exception to it. To estimate the flood risk in Kalam, Pakistan the rainfall runoff modelling of the region was carried out. This involved gathering the hydrological data of SWAT, Kalam region which included the precipitation data as well as the discharge data of River SWAT. A lumped hydrological model HEC-HMS was set up in order to carry out the rainfall runoff analyis. This software gave the discharge values of each year by analyzing the rainfall runoff and topography of the area. From these discharge values the flood risk of the region was estimated. To reduce or mitigate the flood risk a storage dam was proposed. A resrvoir which acted as a storage dam was introduces to the software on the Ushu River in Kalam, Pakistan. This mitigated the flood risk in the region by reducing the stream flows in the wet season.

    Design of storm water disposal system for umt lahore
    (UMT.Lahore, 2019) ZEESHAN TALIB; JAWAD HASSAN; ASHFAQ ALI
    There is severe problem of rain water inundation at UMT campus. Excessive water stands at low spots causing difficulty in movement, soil erosion and deteriorate of surface of land. A storm water disposal system for UMT campus was conceived, planned and designed. The reason of these problems is that campus drain system has been designed only for sewage. In case of precipitation, existing sewer system is not adequate. Due to this reason, precipitation runoff is not drained properly and it flows toward low lying spots and stay in the form of depression pound. A disposal system considering runoff from rain for 10 years return period has been designed. Rational method was used to estimate the storm water runoff which was found as 30 ft3/s. The capacity of reservoir to store water for one hour is 3.14×106 litters. This volume of water can be pumped in 15.42 hours if the capacity of pump is 2 ft3/s.

    Estimation of hydropower potential of upper jhelum canal
    (UMT.Lahore, 2019) Hafiz Syed Naveed-Ul-Hassan; Muzammil Idrees; Ali Hamza Tariq; Muhammad Arslan Shah Hashmi
    This research paper gives the information about the hydropower potential of Pakistan especially at Upper Jhelum Canal. It will also give the knowledge about how we can increase the potential at Upper Jhelum Canal. The type of turbine to increase the potential is also a main factor and the number of urbine and the size that can be used in UJC to maximize the hydropower potential are also mentioned in this research paper. Pakistan is blessed with wonderful hydropower resources about 60,000 MW but we could achieve only 11 percent. In Upper Jhelum Canal the flow varies throughout the year. iiiWe have selected eight different sites of Upper Jhelum Canal with RD (34+750), RD (36+860), RD (63+000), RD (78+695), RD (89+149), RD (107+000), RD (225+080) and RD (348+000) for computing their power potential. Turbnpro software was used in the study for finding hydropower of selected falls. It was used to study preliminary engineering phase process, optimum selection of hydroelectric turbine, their size, type and quantity. It reduces the design time, and provide friendly interface and economical solution of hydroelectric projects. The software proved to be efficient in project feasibility and estimation purpose of different hydroelectric projects. The calculated power on each site were 2520 KW, 2445 KW, 1857 KW, 665 KW, 1092 KW, 1518 KW, 1452 KW and 1205 KW respectively and the total power was found 12754 KW. Percentage difference was calculated between the power calculated by Turbnpro and the power of each site given by irrigation department to select the best possible option for the selected sites. The diameter of runner of each turbine, the length of draft tube for each site, the centerline setting, the gate height of each turbine and the unit speed of turbine in rpm was also computed in the study for each fall structure. The selection of turbine and the number of turbines were based on the energy that can be generated and the unit cost of the turbine. Energy and cost varies with the different available number of falls and their corresponding head available. Powerhouse building and spillways were considered as the main component of civil works. Because of the availability of low head the installation of Kaplan turbine with different capacities are very useful way to get the maximum output. Moreover, this research explains the concept of variations of power, energy and cost in a canal fall hydropower scheme due to various factors as combination of falls to increase the hydropower. This paper will be helpful to attract the new researchers to enhance the hydropower from canals.
