WALL STRUCTURAL

DESIGN LOADS:

THE WALL STRUCTURES HAVE BEEN DESIGNED AND ANALYZED FOR THE FOLLOWING LOADS:

1. DEAD LOAD

2. LIVE LOAD

UPPER RETAINING WALL

a. SURCHARGE: 240 PSF

LOWER RETAINING WALL

a. CONSTRUCTION SURCHARGE: 300 PSF

3. STATIC LATERAL EARTH PRESSURES

UPPER RETAINING WALL BASED ON

c. COEFF OF ACTIVE PRESSURE, Ka = 0.28

d. COEFF OF PASSIVE PRESSURE, Kp = 1.6

LOWER RETAINING WALL BASED ON

a. ANGLE OF INTERNAL FRICTION = 30 DEGREES (LAYER 1 - DUNE SAND), 38 DEGREES (LAYER 2 - ESTUARINE DEPOSITS)

b. SOIL UNIT WEIGHT = 115 PCF (LAYER 1), 125 PCF (LAYER 2)

c. COEFF OF ACTIVE PRESSURE, Ka = 0.40 (LAYER 1), 0.24 (LAYER 2)

d. COEFF OF PASSIVE PRESSURE, Kp = 1.80 (1V:2H), 4.20 (1V:4H)

DESIGN ALLOWANCES:

IT IS ASSUMED THAT SOME OF THE EXISTING SITE PARAMETERS WILL CHANGE OVER THE SERVICE LIFE OF THE FACILITY. THE WALL STRUCTURES HAVE BEEN ANALYZED AND DESIGNED FOR THE

FOLLOWING CHANGES:

1. SCOUR (DEPTH BASED ON CHANNEL MIGRATION)

TIMBER LAGGING:

1. USE PRESSURE TREATED TIMBER FOR THE LAGGING MEMBER, SATISFYING THE SIZES

SHOWN ON THE PLANS.

2. SUBMIT INFORMATION REGARDING THE HARDWOOD SPECIES PROPOSED FOR USE ON THIS

PROJECT FOR ENGINEER'S REVIEW AND APPROVAL, PRIOR TO INSTALLATION.

3. ACCEPTABLE TIMBER LAGGING SPECIES IS DOUGLAS-FIR SELECT STRUCTURAL, OR

APPROVED EQUAL.

4. MINIMUM TIMBER DESIGN VALUES ARE AS FOLLOWS:

BENDING = 1500 PSI

SHEAR PARALLEL TO GRAIN = 180 PSI

COMPRESSION PERPENDICULAR TO GRAIN = 625 PSI

STRUCTURAL STEEL:

1. ALL STRUCTURAL STEEL SHALL BE FABRICATED AND CONSTRUCTED IN ACCORDANCE WITH

THE AISC "STEEL CONSTRUCTION MANUAL,", 15TH EDITION.

2. ALL STRUCTURAL STEEL, UNLESS OTHERWISE NOTED, SHALL CONFORM TO THE FOLLOWING

ASTM SPECIFICATIONS:

W AND MC SHAPES: ASTM A572 (OR A992), GRADE 50

PLATES: ASTM A572 (OR A992), GRADE 50

TIEBACK RODS: ASTM A615, GRADE 80

3. WELDING SHALL CONFORM TO THE STRUCTURAL WELDING CODE, AWS D1.1. USE

LOW-HYDROGEN, E70XX WELDING ELECTRODES.

4. ALL STRUCTURAL STEEL SHALL BE GALVANIZED IN ACCORDANCE WITH THE SPECIFICATIONS.

5. PROVIDE SHOP DRAWINGS FOR REVIEW BEFORE FABRICATION.
