Structural Engineering & Construction Situation 12 (PH)

PAST BOARD EXAM PROBLEMS
Structural Engineering & Construction
Situation 12
Given the following date:
Bolt diameter = 20mmø
Bolt hole diameter = 23mmø
Plate thickness = 25 mm
Bolt shear strength Fvb=120 MPa
Bolt bearing strength Fpb=480 MPa
Plate shear strength Fvp=138 MPa
Fy = 250 MPa & Fu = 400 MPa
1. Determine the max. load P based on the shearing strength of bolts. (339.3 kN)
2. Determine the max. load P based on the bearing strength of plate
(2160 kN); and
3. Determine the max. load P based on the tensile capacity of the plate (1125 kN).

[@NeonRush-kl5yk]

sir tanong ko lang, kelan gagamit ng plus 2 sa bolt hole diameter?

[@cebox]

Based sa NSCP, 2mm kapag ang given ay hole diameter. if bolt diameter ang given, then 4mm. kumbaga, dalawang beses ka magaadd kapag bolt diameter ang give, at isang beses kapag hole diameter ang given.

​​​@@cebox sir bat di ka nag add ng 2 sa hole diameter? sa part 3 ng question. Nagplus 2 ako sa hole diameter sa part 3, Sakto sa sagot yung lumabas. Tama ba na nag add pa ako ng 2mm sa Hole Diameter?

Hi sir, tanong lang po bakit po yung answer ng area gross ang naging answer sa questions #3?
