EVALUATION AND TEST








Destructive and Non Destructive Test
o Evaluation of concrete strength from core test.
Number size and space of steel bars of reinforced concrete by electromagnetic scanning.
Analysis of structural adequacy
Assessment of Foundation
Adequacy of structural loads on winds and earthquake
Evaluation of Column
Evaluation of Beams
Evaluation of Slabs
CONCLUSIONS
 Structure was analyzed under actual present loading conditions and under BNBC 2006 loading
conditions.
 A few numbers of footings have been found marginally un conservative from punching shear
capacity point of view. Safety against bearing capacity bearing capacity of soil underlying few
footing found to vary from 2.08 to 4.29
 Drifts of stories due to the lateral loads found vary from maximum allowable limits specified in
BNBC (2006),Other Conditions are Safe.

Recommendations:


Recommended to remove the machinery equipment’s and 2 over head tanks to reduce the
stress and gravity loads on respective footing and soils. Three footing to be strengthened to
improve the structural safety and soil bearing capacity.
Columns have double story height need to be braced near mid height to avoid Slenderness
effects of the columns
DETAILED DESCRIPTION OF METHODOLOGY
Specification for Detail Structural Assessment
Structural Analysis will be carried on according to BNBC (1993) and ACI code.
I.
Testing of Materials:
 Sub-soil Investigation
 Strength of concrete and steel reinforcement test ( Core cutting, UPV, Hammer Test, Rod
testing)
II.
Investigation of Foundations
 Foundation Explorations
III.
Structural Evaluation (Design check):





Analysis of sub-soil investigations report
Development of computer simulated model
Checking of structural stability and geometry
Checking adequacy of foundation i.e. pile & pile cap or footing/raft
Checking of lateral load resistance capacity of the Building
