Shear Wall and Its Design Guidelines > 자유게시판

Varies from A to E, depending on how the structure is predicted to behave during the occasion of an earthquake which in turn requires totally different stage of detailing requirement. Seismic Design Category (SDC). Varies from A to F, depending on how design and detailing is carried out. Seismic Soil Type. Varies from A to F, relying on how the waves travel via the soil. Seismic Zone. 0, 1, branch cutting shears 2A, 2B, 3 and 4, depending on maximum ground acceleration of a particular area. Low Seismic Risk. Corresponds to zones 1 and 2A of UBC-97, seismic design class (SDC) A and B and branch cutting shears Seismic efficiency class (SPC) A and B. Moderate Seismic Risk. Corresponds to zones 2B of UBC-97, seismic design category (SDC) C and Seismic efficiency category (SPC) C. High Seismic Risk.

Intermediate Moment Frame. A solid in place frame that can resist lateral hundreds by flexural action of its beams and columns and that can present some vitality dissipation, comparatively better inelastic behavior and intermediate ductility in addition to the properties of bizarre moment frames.

However, inelastic habits within the occasion of extreme earthquake is poor. It isn't really useful for seismic zones with larger anticipated seismic exercise. These frames should fulfill ACI 21.2. Special Moment Frame. A cast in place body, having column and shear walls, that may resist lateral hundreds by flexure of its members and has glorious inelastic conduct. The design and detailing of particular moment frames is controlled by ACI 21.5 to 21.8. Structural Walls. Walls proportioned to resist mixture of branch cutting shears, moments, branch cutting shears and axial forces induced by earth quake motions. A shear wall is a structural wall. Intermediate Pre cast structural wall. A precast wall with intermediate inelastic deformation capabilities. Requirements for these walls are given in ACI 21.4. Ordinary strengthened concrete structural wall. It's used to resist lateral hundreds however very restricted inelastic deformation capabilities. Ordinary structural plain concrete wall. It is used for basement partitions for residential or light business buildings in areas where seismic danger is very low. These wall could also be supported by soil, footings, grade beams or other structural members. Special precast structural wall. A precast wall complying with the necessities of ACI 21.8. as well as the necessities of odd bolstered concrete structural and requirements of ACI 21.2 is satisfied. Special bolstered concrete structural wall. A forged in place wall that may be utilized in high seismic exercise areas and has good inelastic deformation capabilities.
