The values are plotted as graph in fig 8. The values are given for EQ-y and they are in meters. Table 5 Represents the displacement in Y-direction. Displacement in Y-direction (EQ-y)įig 6: Selection of the optimal bracings positionįig 6 show how the optimal bracing position is selected by comparing braced frame with G+3 without bracing frame & Bracing cost. Accodingly, minimum lateral drift is achieved.The procedure is shown in fig 6.įig 7: Displacement in X-direction vs Joint No:

By comparing all the results to the cost parameter the optimal selection of the position of X- bracing is verified. The position combination of X-bracings is entered into the design evaluation of SAP2000. In this study 8 models are considered with different bracing combinations as shown in fig 2, 3 & 4. of Earthquakes of Magnitude 5.0- 8.0+ & their return period. Table 3 provides information regarding the No. The bracing used in the model is made of steel.įig 5: Major Zonation and Intensity map in India In model 08, the bracings are provided for G&2 storey in X-Z plane and for 1 & 3 storey in Y-Z plane. The structural data is the same for all the structures.įig 2, 3 & 4 shows the models of steel bracing provided. The loads are provided as per IS 1893:2002 (Part 1). Soil conditions are considered medium stiff and a damping ratio of 5% and the importance factor taken is 1. The X-bracings are provided at the exterior parameter of the structure. Fixed restrains are provided at the bottom. Design data of G+3 storey buildingĬ1=300mmÃ-300mm All column of G.F & Outer columnĬ2=280mmÃ-280mm Interior column for Ist & IInd FloorĬ3=250mmÃ-250mm Interior column for IIIrd floorįig 1 shows a G+3 Storey building with 5 bays in X & Y directions. The table 1 provides data regarding the G+3 storey building. The building is assumed to be located in a seismic zone V and the earthquake zone is plotted using fig 5. The building used for analysis is a four-storied RC building with a floor height of 3m as shown fig 1. Table 2 shows the position of steel bracing. Steel bracing is economical, easy to erect, occupies less space and has the flexibility to design for meeting the required strength and stiffness. The use of steel bracing systems for strengthening or retrofitting seismically an inadequate reinforced concrete frame is a viable solution for enhancing earthquake resistance. Many existing reinforced concrete buildings need retrofit to overcome deficiencies to resist seismic loads. Steel braced frame is one of the structural systems used to resist earthquake and wind loads in multistoried buildings. KeywordsOpen ground storey soft storey bracing lateral stress, cost. The open ground storey creates a soft storey condition. Bracings are provided to arrest lateral stress and prevent swaying of the given structure.
