Dear all,
Three options are available when export floor from Etabs-2013 to safe-v14
EXPORT FLOOR LOADS ONLY
EXPORT FLOOR LOADS AND LOADS FROM ABOVE
EXPORT FLOOR LOADS PLUS COLUMN AND WALL DISTORTION
CSI recommends option number 3 when solving under lateral load, please refer to the...
Dear all,
Etabs2013 asks for system over-strength factor when assigning seismic forces using ASCE-7-05,the program mentioned that this value is used solely in design.
Referring to (ASCE 7-05 Section 12.3.3.3) Required strength of columns supporting discontinuous vertical elements the design of...
Dear all,
[highlight #FCE94F]The wind speed in ASCE-7-10 is given at the strength level value. This differs from previous editions
of the ASCE Standard where service level values were used. ASCE 7-05 design wind
speeds are multiplied by (1.6)0.5 to convert to ASCE 7-10 design wind speeds. ASCE...
Dear all,
When the dynamic analysis method of ASCE-7-12.9 is used, all the requirements of horizontal shear distribution, given in 12.8.4, including torsion calculations that may be accounted for by displacing the calculated centers of mass of each level (see 12.8.4.1 and 12.8.4.2) also apply...
Dear all,
Structures that have horizontal structural irregularity Type 5 in Table 12.3-1 (non-parallel system), ASCE-7-05 requires to take take 100%of seismic force in one direction + 30% of seismic force in the other direction.
Example Ex+0.3Ey.
for the case of doing dynamic analysis (...
Dear all,
as we all know that sap2000 and Etabs gives the moment (m11 , m22 using finite element design method in unit width).
ACI318-08 STATE THE FOLLOWING:
13.5.3.2 — A fraction of the unbalanced moment
given by γfMu shall be considered to be transferred by
flexure within an effective slab...

Dear all
according to CSI recommendations to calculate local p-delta effect
(which is associated with local deformation relative to the chord between member ends)
we have to consider one of these methods:
1-Apply design factors, which ETABS post-processing assumes to be done. These factors...
1-I've heard people say that when you do a second-order analysis on a moment frame, you can use a K-factor of
1.0 for the column design. I'm trying to find an explanation of this concept, and I am trying to find
out whether the idea of using K=1 when you do a second-order analysis is correct or...
Dear all
[highlight #FCE94F]my question seems to be silly !!!![/highlight] but please be patient and think with me about this rule in asce7-05 regarding dual frame system
[highlight #FCE94F](resistance to lateral forces is provided by moment-resisting frame capable of resist 25 present of the...
I made a model for reinforced concrete structure using Etabs
consists of columns shear walls and flat slabs i want the columns to take all the shear force under seismic load case
(my specific question haw can i prevent the shear walls from carrying any amount of the shear forces?????
A dual system, is a structural system with the following essential features:
1. An essentially complete space frame provides support for gravity loads.
2. Resistance to lateral forces is provided by moment-resisting frames capable of
resisting at least 25 percent of the design base shear and...
