This course sets out to give an overview of the types of masonry arch structures encountered by bridge engineers and inspectors on a regular basis across the UK and Ireland highways infrastructure network. It will enable the delegate to think of what the cause of any defect may be, initiate a detailed inspection and once obtaining test results, order the required maintenance. All relevant bridge standards will be shown.
Learning Outcomes:
Each delegate will learn how to identify different defects in both stone and brickwork arches, discover the variety of testing methods which establish the cause of the most common defects. The delegate will discover what relevant information is required in order to carry out a modified MEXI calculation.
Aims & Objectives:
On completion of this course each delegate will be able to examine and identify common defects associated with masonry arches report back and discuss the findings of a defect in a professional manner with other members of the structures team. The course will increase confidence to enable the delegate to give clear instruction to craftsmen to carry out a repair and initiate future maintenance procedures.
Course Outline:
Arch bridge elements
Including a group exercise
Different types and designs of masonry arch
Maintenance
Common issues
Common signs of distress in masonry
Actions recommended when different defects are discovered
Different stone types used
failure issues
corresponding mortar mixes
Multiple arched bridges
Recent and historic arch bridge failures and discussion regarding the possible causes
LANTRA bridge inspection certification scheme
Mode of Delivery:
The course is delivered as a power point presentation with regular discussion and some interactive exercise. There will be question and answer intended to involve the whole group with discussion about nearby structures and individual experiences. Models will be used to increase awareness of structural loading and how it affects the structure.
Benefits Perceived by Participants:
Discover the different types of arch and differences in construction.
Increased ability to communicate with peers on a professional level about masonry arches.
Increased awareness of maintenance requirements.
Increased awareness of distress signs in arches.
What actions to take with different defect types.
Learn what information is required to carry out assessments.
Intended for:
The primary aim is to introduce newcomers to the civil engineering/bridge construction and maintenance industry who have been educated to degree level or those with experience but have a limited knowledge of bridge construction & maintenance or working with masonry arches.
Pre-course Requirements:
A basic understanding of bridge elements and maintenance processes within the organisation is required along with the enthusiasm to improve individual professional awareness.
