Past Experiences
Evaluating of WMATA Aerial Structures Crossing Northeast Boundary Tunnel (NEBT)
Performed detailed analysis of the WMATA bridge within the Zone of Influence (ZOI) of the tunnel based on the as-built plans of the structure. Evaluated the existing condition of the structure by applying permanent and transient loads required by the WMATA design manual. Train live load, impact load, derailment force, and load combinations were per WMATA specific requirements. Applied the impact of tunnel construction activities by imposing support settlements obtained from geo-mechanical modeling. Provided recommendations based on the comparison of the results with and without support settlements. Prepared comprehensive report to present Analysis results and findings.
Empirical and Numerical Geo-Mechanical Analysis for Shafts and Near Surface Structures
Performed detailed empirical and numerical geo-mechanical analysis for different soil profiles. Extracted appropriate information from Geotechnical Baseline Report (GBR) and the Geotechnical Data Report (GDR). Developed geotechnical models incorporating staged excavation, strut installation and preloading, Backfilling and removal of struts. Evaluated model under short term undrained and long-term drained conditions. Applied\Analyzed the impact of jet dewatering, grouting, ground freezing as mentioned in the SOE design package. Provided ground displacement profiles for each construction activity and compiled cumulative settlements for each structure used for classification of unclassified structures based on the contract displacement requirements. Prepared comprehensive reports to present the analysis findings.
Evaluation of 18’ OD Shaft with Steel Ribs and Corrugated Liner Plates
Performed detailed geo-mechanical analysis to obtain lateral forces applied in the shaft surface. Assessed addition loads due to adjacent crane operation. Analyzed the structure under applicable load combinations. Evaluated the structural suffice of the proposed design. Provided detailed analysis report.
Damage Level Evaluation of Building Structures in the Vicinity of Near Surface StructuresPerformed Detailed analysis for buildings per Burland & Wroth (1974) and Burland et al (2008) method at each construction site (total of 7 construction sites). This method incorporates the concept of limiting tensile strain to study the onset of cracking in simple weightless elastic beams undergoing sagging and hogging modes of deformation. Calculated maximum strain due to bending, Horizontal stain, and total strain. Evaluated the significance of maximum strain in terms of damage level. Provided recommendations for reclassification of structures based on anticipated damage level.
Reliability Assessment of Slender RC Bridge Columns
Developed a structural analysis package for RC bridge columns incorporating Caltrans recommendations for P-Delta Analysis (as a part of my doctoral research). Studied the reliability of slender RC bridge columns. Researched on the development of P-Delta limit state which targets to provide an alternative method for the Caltrans criteria for consideration of the P-Delta effects in the design of RC bridge columns. Performed Moment-curvature and pushover analysis on RC bridge column. Performed nonlinear time history analysis with/without P-Delta effects for RC bridge columns. Performed incremental Dynamic Analysis (IDA) to detect the collapse point. Performed Monte-Carlo simulation to study the probability of failure of columns including material uncertainties.
