On the other hand, rigid diaphragms transfer load to frames or shear walls depending on their flexibility and their location in the structure. Diaphragms that cannot be classified as either flexible or rigid are referred to as semirigid. [1] The flexibility of a diaphragm affects the distribution of lateral forces to the vertical components of ...
A classification for the structural system of a high-rise was introduced in 1969 by Fazlur Khan and was extended to incorporate interior and exterior structures. The primary lateral load-resisting system defines if a structural system is an interior or exterior one. [2] The following interior structures are possible: Hinged frame; Rigid frame
Diaphragm valves can be controlled by various types of actuators e.g. manual, pneumatic, hydraulic, electric etc. The most common diaphragm valves use pneumatic actuators; in this type of valve, air pressure is applied through a pilot valve into the actuator which in turn raises the diaphragm and opens the valve. This type of valve is one of ...
RAMP Simulation Software for Modelling Reliability, Availability and Maintainability (RAM) is a computer software application developed by WS Atkins specifically for the assessment of the reliability, availability, maintainability and productivity characteristics of complex systems that would otherwise prove too difficult, cost too much or take too long to study analytically.
Diaphragm (optics), a stop in the light path of a lens, having an aperture that regulates the amount of light that passes; Diaphragm (acoustics), a thin, semi-rigid membrane that vibrates to produce or transmit sound waves; Diaphragm (birth control), a small rubber dome placed in the vagina to wall off the cervix, thus preventing sperm from ...
In structural engineering, a rigid frame is the load-resisting skeleton constructed with straight or curved members interconnected by predominantly rigid connections, which resist movements induced at the joints of members.
In mechanics, a diaphragm is a sheet of a semi-flexible material anchored at its periphery and most often round in shape. It serves either as a barrier between two chambers, moving slightly up into one chamber or down into the other depending on differences in pressure, or as a device that vibrates when certain frequencies are applied to it.
The finite element method (FEM) is a powerful technique originally developed for numerical solution of complex problems in structural mechanics, and it remains the method of choice for complex systems. In the FEM, the structural system is modeled by a set of appropriate finite elements interconnected at
