Challenge 6

1. For Dimensioning of a typical elastomeric bearing following details are required:

a. The Maximum and Minimum Reaction of Various load like DL,SIDL,LL etc (Rapid Loads - LL wind Load etc - Slow loads- DL, SIDL)

b. The rotations of superstructre at bearing locations due to various loads like DL,SIDL,LL etc.

c. Moment of Inertia of Girder Sections at Mid Span

d. Tralslation of Girder at bearing location due to Creep, shrinkage, thermal effects and LL

e. Static and Dynamic shear Modulus of Elastomer, Allowable Stress for Elastomer, Yield Stress of Steel plates

f. Yield Strength of Steel Laminates of Bearing

Notations

a- Length of Elastomer

b- Width of Elastomer

ti- Thickness of Internal Elastomer Layer

te- Thickness of External Elastomer Layer

n- No. of Internal Layers of Elastomer

ts- Thickness of Steel Plate/Steel Laminate

2. The design of elastomeric bearing for question no.2 is presented in attached pdf file.
