Code And Geometrical Consistency Check
Check “Check project consistency before generating reports” in the project settings. The program will list the problematic cases (if
there are) during report generation.
The problems reported in the list should be solved. The items in the list are
explained below.
In one or more stories alphai< 0.70. Increase system rigidity:
The case that the ratio of the shear forces resisted by the strong columns to
the shear forces resisted by all the columns is less than 70%. The column
cross-sections should be enlarged. Subsection 7.3.6 in the earthquake code.
There are objects with insufficient cross-section or not conforming to the
rules in the project:
The errors in elements like column, beam, etc. will be examined and corrected.
There are weak stories with ni<0.60 in the project. Increase system rigidity:
The case that the effective shear area in any story is less than the 60% of
the effective shear area of the upper story. The story having B1 irregularity
will be detected from the story parameters, and the rigidity of the system will be
increased. Clause 6.3.2.4 in the earthquake code.
There are stories not containing shear walls in the project but C16 has been
used as concrete quality:
If there are stories not containing shear walls in systems with high ductility
level, the lowest concrete class necessary to be used is C20. It can be
changed from the project settings. Clause 7.2.5.1 in the earthquake code.
The mode number in the dynamic analysis is not sufficient:
The number of modes that can be defined in the dynamic tab in the project
settings, cannot be less than the number of modes determined in clause 6.8.3.1 in
the earthquake code. Increase the number of modes.
There are story or stories with very high design displacements. Increase
system rigidity:
The design story displacements have to be below the values defined in the
subsection 6.10.1 in the earthquake code. For this reason the system rigidity must
be increased.
Second degree indicator value is very high. Increase system rigidity:
The second degree indicator value have been limited in the clause 6.10.2.1 in
the earthquake code..
“Equivalent Seismic Load Method” cannot be applied in the project. Please perform dynamic analysis:
The conditions defined in table 6.6 in the earthquake code exist in the
system. Select "Mode Superposition Method" as seismic load analysis method from the
project settings and repeat analysis.
There are shear walls in the system but the R coefficient is greater than 7:
In systems with high ductility level if there are shear walls other than
basement panels (defined in the clause 6.7.2.4 in the earthquake code), the
coefficient R in the project settings will be 7.
The R coefficient is 7 and the ratio of total shear wall moments to the total
overturning moments is greater than 0.75:
The coefficient R will be recalculated according to the clause 6.5.2.2. The
alpham values are printed in the reports. The calculated R value will be placed
in the project settings and the analysis will be repeated.
There are slabs with the existing reinforcements less than the required
reinforcements in the project:
There are slabs with insufficient As in the project. Click slab from the RC
menu and check the slabs with insufficient As.
There are beams with the existing reinforcements less than the required
reinforcements in the project:
There are beams with insufficient As in the project. Click beam from the RC
menu and check the beams with insufficient As.
There are columns with the existing reinforcements less than the required
reinforcements in the project:
There are columns with insufficient As in the project. Click column from the
RC menu and check the columns with insufficient As.
There are shear walls with the existing reinforcements less than the required
reinforcements in the project:
There are shear walls with insufficient As in the project. Click shear wall
from the RC menu and check the shear walls with insufficient As.
There are continuous foundations with the existing reinforcements less than
the required reinforcements in the project:
There are foundation beams with insufficient As in the project. Click
continuous foundation from the RC menu and check the foundation beams with insufficient
As.
There are single footings with the existing reinforcements less than the
required reinforcements in the project:
There are single footings with insufficient As in the project. Click single
footing from the RC menu and check the single footings with insufficient As.
Project parameters have been changed but no load analysis have performed:
Carry out load analysis.
Project parameters have been changed but no earthquake analysis have
performed:
Carry out earthquake analysis.
Project parameters have been changed but no 3D frame analysis have performed:
Carry out 3D frame analysis.
Mixed system has been selected but the ratio of the total shear wall moments
to the total overturning moment is less than 0.40:
The condition denoted in the clause 6.5.3.2 in the earthquake code is not
satisfied. (alpham should be less than or equal to 0.40) Increase the number or
the lengths of the shear walls in the system. (You can take EQ code general
report to see in which direction the alpham values are small, and make the changes
in this direction).
Mixed system has been selected, R coefficient is 7 but the ratio of the total
shear wall moments to the total overturning moment is less than 0.75:
The condition in the clause 6.5.4.2 c is not satisfied.
