Abstract: The present invention relates to a multipurpose viscous damper (100), comprising: an outer cylinder (101); a core rod (102) positioned in the outer cylinder (101); a core piston (103) positioned in the middle and surrounded the core rod (102); a plurality of bypass pipes (104) extending along the outer cylinder (101), each bypass pipe (104) being connected to the outer cylinder (101) adjacent to the two ends of the outer cylinder (101); an orifice controller (105) located on the bypass pipes (104) for providing initial adjustable damping during low to moderate vibration; and characterized by a pair of inner cylinders (106) positioned inside the two ends of the core rod (102); an inner piston (107) positioned in each inner cylinder (106); a fixed sealing (108) located at the two end of each of the inner cylinders (106); and an orifice (109) located at the two ends of the inner cylinder (106) for allowing fluid flowing from the inner cylinder (106) to the outer cylinder (101) during movement of inner piston (10

Abstract: The present invention relates to a wall damper (100) connected to an upper floor and a lower floor, comprising of a top cap (108), a pair of cover plates (105), a pair of side members (107), and a base (110), interconnected to one another to form a framing structure to accommodate a pair of inner panels (101), a plurality of damping means (103), and a plurality of outer plates (104); characterised in that the pair of inner panels (101) connected vertically to one another by a joint (102); the top cap (108) having a slit (114) for receiving the pair of inner panels (101); the plurality of damping means (103) bounded to both sides of the pair of inner panels (101); the plurality of outer plates (104) bounded to the plurality of damping means (103); a plurality of stiffening members (106) disposed on a surface of each of the pair of cover plates (105); wherein the pair of inner panels (101), the plurality of damping means (103), the plurality of outer plates (104) and the pair of cover plates (105) are arranged
