For this reason, some steel-RC composite shear walls have been developed and indicated to mitigate most disadvantages of RC shear walls. the structural members studied herein are steel plate-reinforced concrete composite shear walls (SPRCW) by numerical analysis methods. the primary parameters vary in the axial load ratio, the ratio of steel plate and the ratio of web reinforcement in RC shear wall. Numerical analytical results indicate that, compared with the conventional RC

In cases where diaphragms comprise structural sheathing, additional design efficiencies can be incorporated to resist loads normal to walls, floor and roofs using the composite stressed skin action developed between the sheathing and the timber frame. the advantages of timber shear walls and diaphragms include: architectural design freedom (curves, cantilevers, clear spans); lightweight construction; high impact load resistance; resilience (no brittle cracks); fast conventional
the country the "Industrogradnja" system has been successful— ly introduced. the system benefits from the advantages of a fast construction by means of sliding forms. the bearing sys— tem consists of RC shear walls in both orthogonal directions. (Fig. 1 . ) weakened by door openings , as well as of full slabs laid on 3 or 7 lines . Floor slabs are concreted in two or three days after the construction of walls , and connections with the walls is achieved by bars which pass through

This stress arises whenever a section experiences a flexural or restrained warping stress and its magnitude is dependent on the stiffness of the coupling element. Depending on this stiffness, the performance of a coupled section will fall between that of an ideal uniform element of similar gross plan cross-section and the combined performance of the independent component parts. Another advantage of coupling is that it enhances the overall flexural stiffness dis-proportionally to shear

Easy to construct - Easily implemented at site Effective in - Reducing construction cost Minimizing earthquake damage to -Structural elements -Non-Structural elements E.g., Glass Windows, Building Contents advantages of shear
these walls generally start at foundation level and are continuous throughout the building height. their thickness can be as low as 150mm, or as high as 400mm in high rise buildings. shear walls are usually provided along both length and width of buildings (Figure 1). shear walls are like vertically-oriented wide beams that carry earthquake loads downwards to the foundation. advantages of shear walls in RC Buildings. Properly designed and detailed buildings with shear walls have
Both methods have advantages and disadvantages. the segmented shear wall (SSW) approach is the "tried and true" method. It relies only on the segments of full-height sheathing to resist shear, and neglects the effects of sheathing above and below openings. In general it yields a higher design shear capacity than the perforated shear wall (PSW) method. However, the SSW method also requires hold-downs at the bottom corners of each full-height shear wall segment to resist
Steel plate shear walls have been used more and more in the steel structures to resist earthquake and wind forces. This system offers several advantages as compared to the other usual lateral load resisting systems. Steel saving, speed of erection, reduced foundation cost, and increased usable space in buildings are some apparent advantages of the steel plate shear walls. Steel plate shear walls also provide major stiffness against building drift for the hi-rise buildings.

However, the behavior of coupled shear walls is controlled by the characteristics of various coupling beams. these characteristics depend on the following parameters:(1)Beam span to depth ratio.(2)Reinforcement details. For this reason, more study is required to investigate into the limitations on behavior of coupling beams. Since computer programme ATENA2D  has some advantages in comparison with other software packages like SAP V 10.0.5 ,

When shear walls are designed and constructed properly, and they will have the strength and stiffness to resist the horizontal forces. shear walls are not only designed to resist gravity / vertical loads (due to its self-weight and other living / moving loads), but they are also designed for lateral loads of earthquakes / cyclones. . RHCBM walls are constructed by reinforcing the hollow concrete block masonry, by taking advantage of hollow spaces and shapes of the hollow blocks.
Definition: shear wall is a structural member used to resist lateral forces i.e parallel to the plane of the wall. For slender walls where the bending deformation is more shear wall resists the loads due to Cantilever Action and for short walls where the shear deformation is more it resists the loads due to Truss Action. these walls are more important in seismically active zones because during earthquakes shear forces on the structure increases. shear walls should have more strength and
