KEDMOR operates in a highly active seismic environment. KEDMOR provides seismic design and consulting for its in-house projects and bridges, and for other design offices, for large structures, residential and commercial projects, transportation utility (electricity, water, sewage, oil pipelines) infrastructure etc.
The advanced methods used include Push-Over analysis, Time History dynamics, geometrical and material non-linear behavior and Displacement Base Design (DDBD), in accordance with the latest seismic codes.
The expertise of KEDMOR and the resources at its disposal are used for evaluation existing structures as well. Services include seismic risk assessment to support risk management and insurance considerations, earthquake damage vulnerability evaluation, and sustainability assessments.
Seismic sustainability studies include on-site inspections and computerized analysis. Earthquake damage assessments are made, and retrofit and upgrade solutions are suggested to optimize costs of strengthening. Services may be provided up to the level of construction documents, followed by on site supervision. 


Quarry Bridges

Location: Near Nazareth , Israel
Date: Comleted in 2008.
Services: Detailed design and on site services.

General Description
Quarry Bridges are located on road no. 60, near the Iksal junction, above the former "Roichmen Quarry". The superstructure of the two bridges is made of a box girder 3.30m deep. The total width of each bridge is a constant 11m.

The north bridge
The bridge has a total length of approximate 414m, which is divided into 6 spans; 1x 46.6, 2x78, 2x 77 and 1x56m.

The south bridge
The bridge has a total length of approximate 409m, which is divided into 6 spans; 1x 45.4, 2x76, 2x 77 and 1x56.1m.

 

Piers
Pier 2 is much shorter, and therefore stiffer than the other piers of this bridge. A special gap-element at the top of this pier enables the rest of the columns to respond prior to this pier in the event of an earthquake and by that prevent premature failure.

A non-linear gap element was implemented as part of a pushover analysis in order to fine-tune the over-all earthquake response of the bridge.

Construction Method
The bridges designed in two construction methods. The west part of the bridges – cast-in-place Incremental launching.
The east part of the bridges – Precast Balanced Cantilever Method of construction. The maximum length of a segment in the incremental launching method is 22.5 m. The length of a typical segment in the balanced cantilever method is 3 m.
