Item Strength and performance evaluation of nepalese RC bridge pire using nonlinear dyanamic response analysis(2010) Chaudhary, Sikindar Kumar; Roshan TuladharNepal lies in one of the world’s most seismically active region. During the 1995 Hyogo-Ken Nanbu (Kobe) earthquake (M 7.8), highway structures were damaged or severely affected, particularly the single – column –type RC piers. During the 1989 Loma Pita earthquake (M 7.1) in California, widespread damage was reported to the region’s highways and bridges. Five different conditions of Bridge Pier have been considered with investigation of all the database of design available at the DOR. Available bore-hole soil database of the Bridge Pier have been utilized. The analysis showed that the RC Bridge Pier is safer in the event of earthquakes for simulating the ground conditions encircling the pier. The performance of the RC Bridge Pier was accessed in strong ground motion records. In this study it was intended to access the seismic performance of RC bridge piers under Gazali strong motion. It was observed in the field observation that most of the bridges in Kathmandu Valley were having lowered bed due to scouring. The effect of strong vertical ground motion was investigated for possible reduction in flexural and shear strength of the pier. For this purpose, fifteen models have been developed. These fifteen models are grouped into three sets. First set consists of the five models having only horizontal direction of earthquake is applied. Second set consists of five models with horizontal & Vertical direction of earthquake is applied and third Set consist of the five models with Scouring is considered. These studies have revealed that have got profound effect on the performance of the RC structures. The lateral extent of soil mass for each of the five different bridges were fixed based on trial computations until the percentage difference in consecutive response quantities were found within the limit of 0.4%. The lateral extent for the AO is fixed as 400 m ,AW is fixed as 500 m, AP is fixed as 400 m , IP is fixed as 500 m and BPis fixed as 400 m. The light damage, considerable damage and also failure damage of the Bridge pier at different bridges for different cases (AO, AW, AP and BP).The introduction of strong vertical ground motion increase the vertical displacement by 48 % all bridges. It means horizontal ground acceleration (0.71g) and vertical ground acceleration (1.37g) both applied horizontal displacement increases as well as vertical displacement increases. The Nepalese RC Bridge Pier (In 1990-2000) is over safe. The Nepalese RC Bridge Pier (After 2000 & Before 1990) is designed under safe.Item Evaluation of Designers’ Experience with the Use of Electronic Building Permit System (EBPS): A Case Study of Chandragiri Municipality, Kathmandu(I.O.E, 2025-11) Shrestha, Riwaz; Dhital, Mahendra RajItem Analysing Challenges and Behavioral Intentions: A Dual-Perspective Study of Building By-Law Implementation in Kathmandu Metropolitan City(I.O.E, 2025-11) Shrestha, Nishee; Dhital, Mahendra RajItem An Integrated Geospatial Framework for Delineating Groundwater Potential and Building Construction Suitability: A Case Study of Rautahat District, Nepal(I.O.E, 2025-11) Sapkota, Ashok; Shrestha, Santosh kumarItem Risk Assessment of Design and Build Bridge Projects Implemented by Department of Roads in Nepal(I.O.E, 2025-11) Pandey, Aditya; Shrestha, Santosh KumarItem Identifying Key Factors and Formulating a Stakeholder-Informed Framework for Construction Waste Minimization in Building Projects of Kathmandu Valley(I.O.E, 2025-11) Mishra, Neha; Bhattarai, Subash KumarItem Experimental testing and characterization of bambusa balcooa and bambusa nutans for analysis and design of bamboo structures(I.O.E, 2023-12) Poudel, Sarowar; Parajuli, Hari RamItem Numerical Study of Bearing Capacity under Strip footing having underground void : A Case of Lamachaur Pokhara(I.O.E, 2023-12) Nepal, Bibek; Yadav, Santosh KumarItem Prediction of Optimum Bitumen Content in Asphalt Mix Design Using Artificial Neural Network(I.O.E, 2024-07) Giri, Moti Ram; Tamrakar, Gautam Bir SinghItem Post Encroachment Time-Based Behavioral Analysis of Vehicle-Pedestrian Interactions at Unsignalized Midblock Crosswalks: A Case Study of Shantinagar and Dhobighat Crosswalks in Kathmandu Valley(I.O.E, 2025-04) Lamsal, Sandesh; Pradhananga, RojeeItem Evaluating Public Transport Accessibility for Work, Education and Health Trips: A Case Study of Kathmandu Valley(I.O.E, 2025-04) Pandey, Sajan; Pradhananga, RojeeItem Bicyclist’s Perception based Level of Service in Heterogeneous Traffic Condition: A Case Study of Bharatpur, Nepal.(I.O.E, 2025-04) Dhital, Rabin; Marsani, AnilItem Value of Risk Reduction of Fatal Road Crashes: A Case Study of Long- and Medium-Route Public Vehicle Passengers Traveling To and From Kathmandu(I.O.E, 2025-04) Sukubhattu, Puspa; pradhananga, RojeeItem Optimizing Charging Station Locations for Public Transport Route Coverage in Kathmandu Valley(I.O.E, 2025-04) Khatiwada, Purushartha; pradhananga, RojeeItem Calibration of VISSIM Social Force Model Parameters: Case Studies on Signalised Pedestrian Crossings at Min Bhawan and Pulchowk(I.O.E, 2025-04) Shrestha, Pragyan; Shrestha, Pradeep KumarItem An Assessment of Utilization, Compliance and User Awareness of Pelican Crossings: A Case Study of Midblock Crossings at the Gwarko-Lamatar Road(I.O.E, 2025-04) Shrestha, Merina; Marsani, AnilItem 3D Stress-Strain Analyses of Geogrid-Reinforced Pavements under Vehicle Load Configurations and Dynamics(I.O.E, 2025-04) Tiwari, Aanchal; Shahi, Padma BahadurItem Spatio-Temporal Analysis of Road Traffic Crash Hotspots in Kathmandu Valley, Nepal(I.O.E, 2024-07) K.C., Anuradha; Pradhananga, RojeeItem Assessing Service Quality of Ride Hailing Bike Service within Kathmandu Valley(I.O.E, 2024-07) Chaudhary, Ambika; Shrestha, Pradeep KumarItem Performance Evaluation of Ekantakuna Intersection(I.O.E, 2025-04) Kafle, Shesh Raj; Shrestha, Pradeep Kumar
