This equipment allows measurement of strain hence bending moment along the length of the vertical and horizontal members of a rectangular portal frame. It is to be used with ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

Strain gauges are fixed at equal distance along the frame members, 8 on the horizontal member and 4 on each vertical member. Both vertical legs of the frame can be clamped to ST300 Universal Structural Frame. Loads can be applied on the horizontal and/or vertical members and/or removable moment arm of the frame. Strains on the frame can be measured by the strain indicator. Bending moment at each strain gauge can be calculated from the strain and compared with the theoretical value.

Instruction manual is also included.

This equipment allows comparison of experimental and theoretical deflections and reactions of a rectangular portal and an “S” frame when loads are applied. It is to be used with ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

The frame is made of steel bar with a fixed leg while the other leg can be moved horizontally. Loads are applied vertically and/or horizontally. Moment at the frame fixed leg is measured by a moment support and a horizontal force on the frame free leg is measured by a horizontal force support. Deflection of the frame is measured by a dial indicator.

This equipment allows measurement of axial forces in pin-jointed truss members and compare them with calculated values. It is to be used with ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

The truss consists of 19 members for construction of different cantilevered trusses where loading can be applied at any of the bottom joints by a load hanger and weights. An indicator measures truss deflection. The joints are designed to simulate pin-joints. Each truss member has a strain gauge. Each strain gauge is wired to form a full bridge with temperature compensation and zero adjustment in the strain indicator. A steady bar with three adjustable forks is provided to ensure lateral stability. 

Instruction manual is also included.

The equipment allows measurement of deflections and axial forces in pin-jointed truss members when a redundant member is added. It is to be used with ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

A wall mounted truss frame has a pinned upper joint and the lower joint a roller bearing on a support. There are 7 truss members and an extra member with an adjustable length. Load is applied by a load hanger and weights. Deflection is measured by a dial indicator.  Each truss member has a strain gauge which is wired to form a full bridge with temperature compensation and zero adjustment in the strain indicator.

Instruction manual is also included.

The equipment is used for applying the principle of virtual work to the derivation of redundant reactions. It is to be used with ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

An elastic beam is supported at both ends by one moment support and one built-in / knife edge support.  Moment support permit the application and measurement of moment and rotation.  A vertical force support, is used for the case of two span continuous beam. A clamp on moment application device with a mean to counter balance the device weight is provided to apply a pure moment and measure rotation. The beam is loaded by weights. The deflection and slope of the beam can be measured by dial indicators.

Instruction manual is also included.

The equipment is used for measurement of deflections and slopes of a beam under bending or and compare with values calculated by differential equation. It is to be used with ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

The beam rest on two built-in/knife edge supports. Load hangers are used for point loads and a number of weights are used for uniform load.  Deflections and slopes are measured by dial indicators.

Instruction manual is also included.

The equipment is used for measurement of the reactions of a two-span continuous beam with and without settlement of a support. It is to be used with ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

The equipment consists of a beam, two vertical force supports and a built-in/knife edge support. The settlement of each load measuring support is measured by a dial indicator and can be simulated by height compensation mechanism.  Three movable load hangers with a set of weights for downward as well as upward loading are provided. Each beam deflection is measured by a dial indicator.

Instruction manual is also included.

The apparatus is used for studying a cantilever deflection and determining shear center when the plane of loading does not co-inside with the axis of symmetry of the cross section. It is to be used with ST305 Universal Base Frame or ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

The cantilever under test is mounted horizontally on a support column at one end. The mounted end can be rotated to indicate its position relative to a fixed angular scale. Load is applied through a weight hanger and weights at the free end. A circular disc is attached to the free end and vertical and horizontal displacements may be measured by two dial indicators. The pin where weight hanger is hung can be moved laterally on the circular disc across and outside the section of the cantilever to determine shear center.

Instruction manual is also included.

The equipment is used for studying the plane of traverse loading without twisting for selected standard sections. It is to be used with ST300 Universal Structural Frame (separately supplied) for attachment of the accessories.

Interchangeable beam specimens are made from steel sheet or approximate equal with welded-on end plates and a central loading plate which has a provision at the bottom for loading at different eccentricities from the beam axis. The end plates are attached to two flanged supports. A load is hung at the bottom of the central loading plate and two dial indicators are used to measure deflections of both ends of the plate.  The plane of zero twist is the plane of shear center.
