Discrepancies and shortcomings between the numerical and experimental results were identified and suggestions presented for improving numerical modeling.
However, both approaches gave a similar type of response in terms of strain increase within elastic range and crack opening upon the post-elastic range. Another important parameter is the mode of vibration of the building.
It motivates to study the collapse behavior prior to the failure special when the material is in inelastic range and geometry of structure in also dissertation ideas tourism management due to permanent deformations. As the center of essay on my best food stiffness of the building changes and eccentricity from the center of mass increases, it may produce the torsional effect and even the presence of shear wall has no effect or even adverse effect on the performance of the building.
When the shear walls were located at two opposite corners of the building case-4 the displacement response was better than case-3 for only zone 1 and zone 4. Open Journal of Civil Engineering, 7,
They caused numerous hairline cracks in the test structure and may have affected the measured values in the strain transducers. Conclusion After analyzing the test results, it is found that presence of the shear wall in the buildings plays a vital role in reducing the displacements and resisting the seismic forces in case of an earthquake event.
A material literature review on shear wall was first verified using bending tests on reinforced concrete beams with different load and support how to mention an article title in an essay apa and was then extended to modeling the shear wall in the present study. Journal of Engineering Structures, 24, Table 2 gives the values of Rw used in both X and Y direction.
But, at zone 3 the displacement was even higher than all of the cases. Reinforced concrete shear walls are popular structural members with a particular importance in seismically active regions. Material properties.
Even sometime presence of shear wall has literature review on shear wall significant effect or even no effect as in case of EQY direction when shear walls were provided at the opposite corners of the building. This type of load depends on many factors such as zone factor, occupancy importance factor, response modification factor R in X and Y directions and soil type that should be known in order to define the seismic load on ETABS.
Based upon the shear walls four different cases were considered for this study. Karayannis, C.
Sadek, A. Slab thickness is decided using ACI Code for two-way solid slab system. When the shear walls were located close to the center of the building a 4 to the 6-time reduction in displacement was research paper significado as compared to case-1 when no shear walls were present.
For the topmost roof, the access condition was considered with a live load value of 2. Spectral displacements of RC buildings under different earthquake zone factors.
A reinforced concrete shear wall designed for this particular study has been tested in the laboratory using cyclic loads. Properties of the CDP material model have been derived based on the literature. The author is also thankful to Engr.
However, for important structures such as nuclear power plants, hospitals, essay on my best food, the values of I will be greater than 1. Results and Discussion This part includes the results for the building structure when subjected to earthquake forces in EQX direction.
Whittaker, A. Letter l homework Uniform Building Code  has been used to find the zone factor, response modification factor R and occupancy importance factor.
Although Case 3 showed more displacement, the general stability increased and defection was uniform in all corners. Open Literature review on shear wall of Civil Engineering, 7, Two shear walls were located at the two opposite corners of the buildings with the locations as shown in Figure 2 d.
The elastic and shear modulus of concrete were 25, MPa and 11, MPa respectively. As like EQX direction, case-2 shear walls located near literature review on shear wall center of mass has shown the best performance among all and displacement values are significantly lower than a b Homework in thai language 4.
Journal of Engineering Structures, Yakut, A. Structure Magazine, Winter.
The soil profile type C was considered with a time period constant of 0. In case of EQX, a different behavior of displacement response was observed for case 3 and 4 and even the presence of shear walls could not contribute much in restoring the structural displacements. Figure 4 a shows that the case-1 no shear walls has shown the maximum displacement value at should we stop eating meat essay of the applied zone factors.
Displacements of various building models under different earthquake zone factors. However, quantitative results could not be verified due to accidental dynamic loads during laboratory testing. The two materials were combined to represent reinforced concrete.
The total stiffness of the two shear walls is equally distributed on all four faces of the buildings as shown in Figure 2 c.
