i hv solve one RCC building in Etabs considering dynamic effects using response spectra method an i m getting natural period 2.37 sec an base shear 1319 kN. An i hv solved same problem manually also i got natural period 0.97 sec and base shear 1320 kN but , the problem s that natural period by manually an etabs r not matching plz some one help me i m attaching etab file also.
these r the details of building
Live load : 4.0 kN/m2 at typical floor
: 1.5 kN/m2 on terrace
Floor finish : 1.0 kN/m2
Water proofing : 2.0 kN/m2
Terrace finish : 1.0 kN/m2
Zone III : Z= 0.16
Earthquake load : As per IS-1893 (Part 1) - 2002
Depth of foundation below ground : 2.5 m
Type of soil : Type II, Medium as per IS:1893
Storey height : Typical floor: 5 m, GF: 3.4 m
Floors : G.F. + 5 upper floors.
Plinth level : 0.6 m

Earthquake Spectra - February 2010 Volume 26 Issue 1 pp. 1-310
Earthquake Spectra, the professional journal of the Earthquake Engineering Research Institute (EERI),
is published quarterly in both printed and online editions in February, May, August, and November.
The printed edition is sent to EERI members as part of their membership benefits.
EERI established Earthquake Spectra with the purpose of improving the practice of earthquake hazards mitigation, preparedness, and recovery.
It is intended to serve the informational needs of the diverse professionals engaged in
earthquake loss reduction: civil, geotechnical, mechanical, and structural engineers; geologists, seismologists,
and other earth scientists; architects and city planners; public officials; social scientists; and researchers in all these disciplines.
Spectra serves as the publication of record for the development of earthquake engineering practice, earthquake codes and regulations,
earthquake public policy, and earthquake investigation reports. Manuscripts published in Earthquake Spectra are peer reviewed.
Periodically, EERI publishes special issues of Earthquake Spectra, either as theme issues or as reconnaissance reports on major earthquakes.

Hi All,
I thought would it be good if we create a group in facebook so Civilea would get famous and more exposure. So that more people can find it useful in turn they could contribute back. I want permission from Creator,moderators and members to do, so that there wont be any conflicts later. Comments on this??
Essential tips for independent
contractors and consultants
As a consultant, you face the challenges of meeting clients’ needs, soliciting new business, keeping your
skill sets current, and many other daily activities. It’s not easy, and some days it probably seems
overwhelming.
To help you along, we’ve compiled a group of articles written by Meredith Little, a frequent contributor to
TechRepublic. She works as a self-employed technical writer, documentation specialist, trainer, and
business analyst. We think you’ll agree she’s well qualified to address issues facing IT pros who work
independently.
If you’re just beginning to explore the notion of becoming an independent contractor, the first article in
this series will help you determine whether you have what it takes. Next, Meredith explains what
separates consulting and contracting, and offers tips on deciding how to classify yourself. Finally, a threepart
series on protecting your own interests in your contracts presents pointers on ensuring that you
never get burned again.
