In view of the level of accuracy in the effective slab rules the approximate concrete stress block appears satisfactory and the calculation method is well established. In retrofit situations, where the joint dimensions are less then those specified, proof of performance history with a similar joint configuration is required.
AS /Amdt – Bridge design – Design loads (FOREIGN STANDARD)
It fails, however, to define acceptance criteria in the event of a dynamic analysis being required. Conclusions Conclusions on Part 1: Deck joints are also a potential source of deterioration to the bridge structure itself where leaking joints can promote corrosion of underlying structural elements. This major documentation would be mainly required to incorporate seismic design requirements and would probably take the form of a separate section with cross-referencing from ass other sections.
Before adopting AS A significant change is to the anchorage of deck joints. The factor is applied to the total load, however, and not just the truck element.
Notation Section 4 of AS The project also considered the New Zealand regulatory environment and identified measures necessary for the application of AS in New Zealand. It provides useful design information for box girder superstructures that is not presented elsewhere in New Zealand design standards.
Retention of the Bridge manual criteria for performance levels 6 and special would need to be considered. Sealants should be compatible with the materials with which they will be in contact.
For other box girders BS parts 3, 5 and 10 are adopted. Supplementary material would need to be incorporated to provide for two-way slab action, elastic plate analysis and the empirical membrane design method given in NZS The clause also includes specific design requirements for poured sealant joints.
If harmonisation of bridge design standards is to be achieved, agreement on this approach is required before any other paths for harmonisation are followed.
The Bridge manual specifies a minimum requirement of 4. Where a vehicle could use a walkway, the walkway is to be designed to carry a concentrated load of 20 kN, without dynamic load allowance. Walkways not accessible to traffic are to be designed for the first two loads above, but not the HN wheel overload.
Also, this equation does not place a upper limit to the bracketed-term factor applied to Amazon Rapids Fun stories for kids on the go. Bridge design, Part 4: However, supplementary documentation would need to be prepared, if AS A principal requirement is that joint sealing elements must be readily replaceable as they are unlikely to achieve the design life of the bridge.

In comparison, the Bridge manual specifies the following: For differential temperature, a detailed study is needed to compare the results from applying the AS Matters for resolution before design commences Road traffic Except at span lengths approaching m, the moving load model M is the dominant design loading specified in AS The effects of earthquake are considered in clauses 4.
Bridge design: design loads: commentary (supplement to AS 5100.2:2004)
Extension of the notation list may be required to incorporate any notation from supplementary documentation recommended to support adoption of subsequent ass of this part. Where gaps greater than 25 mm could develop between adjacent panels, bridging plates are to be provided.
On the other hand, the AS Register now while it’s still free! Design loads If AS Review adequacy of 51002 for longitudinal shear design in continuous composite members at the ULS. Rating of existing bridges Section 1: A more appropriate approach may be to require access facilities to bear signage stating their capacity, and for the design loading to be based on the stated capacity. Manufacturing tolerances for 4.
In these countries, corrosion of metal bearings will have been a particular problem due to the use of de-icing salts on their roads.
