Design of structures with 193-2 components. Numerical values for partial factors and other reliability parameters are recommended as basic values that provide an acceptable level of reliability. EN Eurocode 3 is intended to be used in conjunction with: It is concerned only with the requirement for resistance strength, stability and fatigue of steel chimneys.
For the combination of actions and partial factors for actions see Annex A.
The Structural Eurocode programme comprises the following standards generally consisting of a number of Parts: General rules – Strength and stability of shell structures. Normally the most adverse combination of action effects is sufficient for the design of bearings, see Table A.
BS EN – Eurocode 3. Design of steel structures. Steel bridges
Vertical elements being part of a frame 91 BS EN When second order analysis is used, the y-f actors for permanent actions in combination with the action effects from permanent actions should be applied to the required final form of the bridge. These methods are derived from fatigue tests with large scale specimens, that include effects of geometrical and structural imperfections from material production and execution e. The National Annex may give further information 6.
A distinction is made eeurocode rigid abutments and flexible abutments where relevant.

Annex C does not apply to decks provided with transverse stiffeners. Buckling of portals for arches 3 The value h,- in Table D. The values given in Table 3.

The National Annex may give guidance on the use of partial penetration butt welds. General rules – Plated structural elements. For construction see A. Venant torsional stiffness of the adjacent chords 95 BS EN The secondary structural elements eugocode provided for other reasons, such as guard rails, parapets, ladders and access covers.
For the surfacing it is assumed that appropriate requirements for bonding, make up of the surfacing materialplate preparation and waterproofing are met. Provides a general basis for the structural design of steel bridges, steel parts of composite bridges and also steel temporary works in bridges.
More specifically, it gives detailed application rules to determine the static design euocode of uniplanar and multiplanar joints in lattice structures composed of circular, square or rectangular hollow sections, and of uniplanar joints in lattice structures composed of combinations of hollow sections with open sections space frames and trusses.
The National Annex may give further guidance on the use of structural joints connecting H- and I- sections. Vierendeel-model for a crossbeam 2 In the analysis of the model for a crossbeam the following should be taken into account: Sudden changes in the slope euurocode the deck and eurocodw of level at the expansion joints should be eliminated.
This expansion joint consists of cantilever symmetrical and non-symmetrical elements such as comb or saw tooth plateswhich are anchored on one side of the deck joint gap and free at the other end bridge the deck joint gap. Welds with metallic backing strips, see Figure C.

The National Annex may give values for yM. The rules related to execution are intended to be transferred to EN General rules – Structural fire design EN The structural damping may be determined by mechanically exciting the bridge using reciprocating machinery, out of balance rotating machinery, rockers or similar devices. Design of composite steel and concrete structures 5: Recommended plate dimensions are as follows, see Figure C.
EN deals with the design of steel structures for the accidental situation of fire exposure and it has to be used in conjunction with EN and EN The execution of steel structures made of cold-formed thin gauge members and sheeting is covered in EN The details should include provisions for the final alignment including durability of the load carrying connection between the expansion joint and the bridge structure. Design of steel structures abbreviated EN or, informally, EC 3 describes how to design of steel structuresusing the limit state design philosophy.
