SUMMARY:Online Workshop - Serviceability Effects of Foundation Movements and Deterioration on Bridge and Approach Structures (Day 1 of 1)
DESCRIPTION:Purpose and Background \nFoundations for bridges and approach structures should be designed so that their movements will not damage the bridge superstructure and associated structures such as abutments and approach slabs. Various aspects of movements that should be considered in the design of bridges include (a) the effect of uneven (differential) settlement between various support elements\, (b) the rotation and horizontal movements of the foundation system affecting movements at the bridge-seat level; (c) movements due to material deterioration; and (d) serviceability problems near a bridge abutment and approaches. The presentation will be based on latest (2020) version of the Bridge Design Specifications (BDS) and the Load and Resistance Factor Design (LRFD) platform of the American Association of State Highway and Transportation Officials which is a key component of Federal Highway Administration (FHWA) guidelines for this topic. Information on Extended Service Life (ESL) and Protection Index (PI) concepts from AASHTO’s latest (2020) Guide Specification for Service life design will also be presented. \nBenefits and Learning Outcomes \nUpon completion of this course\, you will be able to: \n\nRecognize the interaction between foundations and bridge structures.\nExplain the modes of foundation movements.\nComprehend the construction-point approach.\nDiscuss the effect of foundation movements on bridge superstructures.\nExplain the effect of movement of approach structures on abutments.\nIdentify and understand the tolerable movement criteria.\nComprehend the SE load factor and its application.\nIdentify the various provisions related to foundation movements of the AASHTO LRFD Bridge Design Specifications\nExplain the new AASHTO Guide Specification for Service Life Design.\nFoster a better understanding of the serviceability effects of foundation movements by structural and geotechnical specialists involved in bridge designs.\nRecognize potential problems for bridge structures related to foundation movements.\nExplain the need to have enhanced understanding of the interaction between bridge superstructure and foundations.\nExamine the possibilities and benefits of improved communications between geotechnical and structural specialists for bridge foundation design\n\nAssessment of Learning Outcomes \nStudents’ achievement of the learning outcomes will be assessed via a short post-assessment (true-false\, multiple choice and fill in the blank questions). \nWho Should Attend? \nGeotechnical specialists\, structural specialists\, bridge designers \nOutline \nUsing a collaborative and interactive learning approach\, this virtual workshop will help you understand: (a) the types of foundation movements and the uncertainties associated with them\, (b) the construction-point concept and the SE load factor\, and (c) the effects of foundation movements on bridge superstructure and appurtenant structures. The workshop will help you assimilate these crucial considerations through active participation by frequent interactions throughout the workshop and real-time expert feedback. The interactions will facilitate a better understanding of the nuances of the various design procedures which would help you avoid costly design errors in real-world projects. In between the two live sessions\, attendees will independently work on an application (e.g.\, exercises) or a reflection (e.g.\, reading) assignment. \nDay 1 of 2 \n\nIntroductions\nTypical components and terminology for bridge structures\nTypes of bridge foundations and abutments\nModes of foundation movements\nEffect of foundation movements on bridge superstructures\nEffect of movements of approach structures on abutments\nTolerable values of movements\nConstruction-point approach\nReview of Day 1\nInteractive Question and Answer (Q&A) session\nAssignment of homework\nAdjourn\n\nDay 2 of 2 \n\nRoadmap for Day 2\nReview of homework assignments and recap of Day 1\nAASHTO LRFD Articles relevant to foundation movements\nThe SE load factor\nExample Problem: Application of the SE Load Factor\nDifferential settlement: Sf-0 and NPEC Approaches\nExample: Incorporation of Foundation Movements in Bridge Design\nMaterial Deterioration: AASHTO Guide Specification for Service Life Design\nReferences\nClosure\nReview of Day 2 and full workshop\nInteractive Question and Answer (Q&A) session\nAdjourn
