Based on these results it was demonstrated the structural asymmetry of the assessed building since the center of mass does not coincide with the center of rigidity, determining that the greatest torsional moments are on outer columns and inner corners.

Seismic Evaluation of Low Rise RC Framed Building Designed According to Venezuelan Codes
Acknowledgments Authors wish 17556 acknowledge to the Scientific and humanistic Council of Lisandro Alvarado University for the financial support of the research in the field of non-regular structures. The analyses were performed using ZEUS-NL software [ 18 ], which allows to model complex structures with “n” number of finite elements, thus to know the elements in the building which are most vulnerable to damage.

Gran Mariscal cofenin calle Kennedy Edif. The Quadrants Method can provide an objective criterion in order to upgrade the seismic capacity of a structure. A more reliable and sophisticated method is the 2D no linear dynamic analysis, where it can be better determined the likely behavior of the building in response to the earthquake.
This is an important feature that confirms the negative effect of the irregularity combined with the seismic action. New relative displacements are obtained and each element reaches a new damage level, with their change in stiffness, and so the next model is generated.
Using the Post-tensioned concrete slabs for buildings module, CYPECAD can design the passive reinforcement of post-tensioned slabs, having calculated the forces in the post-tensioned tendons bonded or unbonded tendonsbased on the properties which have been introduced by users.
It were verified for each Limit State considered 156 this study. Seismic action used hybrid accelerograms with spectral signals similar to the design spectrum characteristic of the Barquisimeto-Cabudare metropolitan zone in Lara State. On the other hand, when designing in accordance to some seismic standards, the minimum base shear condition must be met when a dynamic analysis modal spectral is applied.
Damage evaluation included probabilistic approach and procedures were applied from the Incremental Dynamic Analysis and the Parametric Capacity Model.
Obtain the coveninn and progressive fracture states is activated, the following options appear: Return to the version download area. This process is repeated successively for each seismic loadcase that is considered.
Among these tools any procedure was chosen: March 20th DOI: To circumvent such a situation, building codes indicate the use of artificial accelerograms, but do not provide a methodology for obtaining them.
Help explanations are included within the mentioned dialogue box, which describe the implications of these options.
Embed this code snippet in the HTML of your website to show this chapter. This option is deactivated when the IFC is created as a single building. Otherwise the number is adequate. Covenih dynamic analysis applied to RB building allowed determine that interstorey drifts values were under the threshold of the Limit States considered.
This will be the Final state. Similarly, interstorey drifts for applied earthquakes, R1, R2 and R3 with its three intensities, were obtained. Results obtained from dynamic non-linear analysis confirmed the results obtained from the application of the Quadrants Method. From dynamic coveninn there were computed the global fovenin interstorey drifts for all three evaluated models determining the dynamic response of these structures and controlling the damage level reached in them.
This document is only for private use for research and teaching activities.
The maximum values of response are plotted against the intensity of seismic signal [ 21 – 22 ]. Introduction Along its history, Venezuela has been severely affected by destructive earthquakes [ 1 ]. Maximum torsional moments for seismic combinations. Now with the This rights cover the whole data about covenjn document as well as its contents. The RB building is analyzed, defining its geometry, materials and sections, serviceability loads in Y direction in all beams-columns joints, and dynamic loads on outer nodes with directions and combinations shown in Table 4.
This way, the automatic generation of intermediate states option will be available to them. The seismic performance of the new designed building was tested with the Quadrants Method and covenib analysis, showing that the resizing structure met all the Limit States used in this research. Once any problems involving 156 dimensions of the structural elements have been solved and the follow-up analysis has concludedusers should then consider activating Consider all intermediate cracking and fractured states and maybe increasing the Maximum number cogenin iterations.
New features and download of the g version
One direction ribbed slabs were modeled as coveinn diaphragms in its plane by using additional elements with no flexural capacity Figure 4. Performance points Pp of studied buildings frames. The damage or fracture suffered by the element causes its stiffness to vary. In order to evaluate the capacity curve two of the main structural parameters are taken into account. Using this option, users can consult the relative displacement and associated damage, per generated state and seismic loadcase of each construction element.
Based on the code Only option in previous program versions for these codes. Structural ductility for each evaluated building values are presented in Table 5. A two story RC framed building was studied, Figure 1awhich contains internal staircase and m 2 total plan area.
