Effect of Seismic Load on Column Forces in RC Structures by Response Spectrum Analysis
In the present research work 30 story building with different type of RC Shear wall at the center in concrete frame structure with fixed support conditions under different type of soil for high seismic zone are analyzed. This paper aims to study the effect of seismic load on column forces in different type of RC shear walls in concrete frame structures under different type of soil condition and different load combination. Estimation of column forces such as; column axial force, column moment, column shear force, column torsion, time period and frequency and modal load participation ratios is carried out. In dynamic analysis; Response Spectrum method is used. It was found that the axial force and moment in the column increases when the type of soil changes from hard to medium and medium to soft. Since the column moment increase as the soil type changes, soil structure interaction must be suitably considered while designing frames for seismic force.
Response Spectra Study of High Rise Structure with RC Shear Wall by Considering Lateral Loads and Storey Stiffness
The present study aims at evaluation of the behavior of a high rise structure with dual system for estimation of structural response lateral loads and storey stiffness has been studied. To meet this objective, G+29 storey building with C shape, Box shape, E shape, I shape and plus shape of RC shear wall, at the center in concrete frame structure with fixed support conditions under different types of soil for high earthquake zone are analyzed by dynamic analysis in ETABS software. It was found that the building with box shape shear walls provided at the center core showed very significant performance in terms of lateral loads and storey stiffness. It was found that the behavior of new shape (plus shape) of shear wall is similar to I and box shape. For severe lateral loads caused by wind load and or earthquake load, the RC shear wall is obvious.
Study the Impact of the Drift (Lateral Deflection) of the Tall Buildings Due to Seismic Load in Concrete Frame Structures With Different Type of RC Shear Walls
Story Drift is defined as the difference in lateral deflection between two adjacent stories. Lateral deflection and drift have three effects on a structure; the movement can affect the structural elements (such as beams and columns); the movements can affect non-structural elements (such as the windows and cladding); and the movements can affect adjacent structures. Without proper consideration during the design process, large deflections and drifts can have adverse effects on structural elements, nonstructural elements, and adjacent structures. Drift problem as the horizontal displacement of all tall buildings is one of the most serious issues in tall building design, relating to the dynamic characteristics of the building during earthquakes and strong winds. Drift shall be caused by the accumulated deformations of each member, such as a beam, column and shear wall. lateral forces due to wind or seismic loading must be considered for tall building design along with gravity forces vertical loads. Tall and slender buildings are strongly wind sensitive and wind forces are applied to the exposed surfaces of the building, whereas seismic forces are inertial (body forces), which result from the distortion of the ground and the inertial resistance of the building. These forces cause horizontal deflection is the predicted movement of a structure under lateral loads and The structural prototype is prepared and lots of data is been collected from the prototype. All the aspects such as safety of structure in shear, moment and in story drift have been collected. Main problems that would be arising due to earthquake in the structure are story drift and deflection of the building due to its large height and also torsion and others, so if the structure is proved to be safe in all the above mentioned problems than the structure would be safe in all cases in respect earthquak e.
