Enercalc Version 5.8

[Subject Prev][Subject Next][Thread Prev][Thread Next]

 

had recently downloaded the new Enercalc Version 5.8 Demo version and have the following comments / questions :

1) The new version had claimed to be updated to meet IBC 2003 requirements, but majority of the forms were still computed based on the old UBC 94/97. (i.e Masonry wall, concrete calculations referring to seismic zones, seismic zone factors, special inspection requirements etc. They hsould be modified to meet the requirements of ASCE 7-02, ACI 530-02 and ACI 318-02).

2) New Forms for Seismic Analysis – Spectra response accelerations based on 0.2s and 1.0s S(s) and S(1) appears to be significantly lower compared to 1996/2002 USGS Seismic Hazard maps.

3) New Forms for Seismic Analysis – Automated computation of the site coefficient, Fa was incorrect. The program shows to use a site coefficient, F(a) of 1.2, is this correct ? My IBC table 1615.1.2(1) shows a F(a) value ot 1.6 for Ss <= 0.25.

Had anybody had a chance to verify the results of this latest version yet ?
