EVALUATION AND TEST






Destructive and Non Destructive Test
o Evaluation of concrete strength from core test.
o Verification of Rebar of structural members by Ferro Scanning
Analysis of structural adequacy
Assessment of Foundation
Evaluation of Column
Evaluation of Beams
Evaluation of Slabs
10 STORY BUILDING:
CONCLUSIONS
 Structure was analyzed under actual present loading conditions and under BNBC 2006 loading
conditions.
 Considering 4935 psi concrete strength, it was found that all the beams and slabs are adequate
according to BNBC 2006 . The column and footings are adequate considering actual gravity
loading (Dead load and present actual load). However according to BNBC 2006 (Considering
Earthquake and Wind Load) most of the columns are overstressed.


Considering 3383 psi concrete strength , it was found all beams and slabs are adequate
according to BNBC 2006. The column and footings are adequate considering actual gravity
loading (Dead load and present actual live load ) condition. However according to BNBC 2006
(Considering Earthquake and Wind Load) all of the columns are highly overstressed.
Recommendations:



Recommended to retrofit all the column and footings to make the structure compliance with
BNBC 2006.
Ensure that floor load is within the allowable limit.
Recommended to engage a load manager immediately.
9 STORY BUILDING:
CONCLUSIONS
 Building was analyzed as per the live loading conditions and 63 psf live load. All the center
columns are marginally adequate considering the concrete strength suggested by ACI 562
(Without considering any lateral load slenderness effect in column at ground level) in actual live
load. The edge and corner columns are not adequate for this reduced loading conditions.
However, considering BNBC 2006 with all its loading combinations(gravity and lateral load) most
of the columns are highly overstressed.
 For the existing loading conditions (Excluding lateral load) most of the beams are adequate.
However considering BNBC 2006 with all its loading combination (i.e. gravity and lateral load )
some of the beams are overstressed.
 We found that factory of safety of four foundations among twenty four between 1.1 and 1.5 and
seventeen foundation among twenty four less than 2.0. This assessment was done subsoil
investigation of Geotechnical engineers and consultants in March 1993.
 Slab is adequate in actual live load conditions.
RECOMMENDATIONS:



Recommended immediate rectification works for adequate /overstressed structural members
and practice safety measures before starting rectification work.
Recommended to remove heavily loaded water tank from roof.
Recommended top replace the brick wall of toilets with lightweight Aluminum sheet or
equivalent partition wall in all floor except ground floor.
