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
CONCLUSIONS:





We found equivalent strength of concrete 4,668 psi according to ACI 562.
All slabs were found adequate considering BNBC 2006 load combinations (considering live load
63 psf as well as 42 psf).
Considering all the load combinations of BNBC 2006 (i.e. gravity and lateral load) and the
concrete strength suggested by ACI 562, 35 columns were found overstressed considering live
load 63 psf (see details in Chapter-4) and those are overstressed in seismic loading combination
only. The number of columns need to be retrofitted might be changed after the retrofitting
design.
All beams are adequate considering BNBC 2006 with 63 psf live load.
Considering BNBC recommended live load 63 and 42 psf, all the individual footings were found
adequate (factor of safety more than 1.5). Mat foundation is adequate for punching shear
considering 63 psf live load. It is also found that minimum reinforcement has been given in mat
foundation.
RECOMMENDATIONS:



The DEA study team of EIMS hereby recommended that rectification design should be carried
out to strengthen overstressed members (due to lateral load; earth quake load) found in this
study to comply with BNBC 2006.
We recommend to relocate heavy storage (more than 100 psf) from overloaded locations of 1st
floor immediately.
