Diaphragm actionFloor structureSeismic behaviorSeismic loadRigid diaphragmFlexible diaphragmDiaphragm action in floor structures is an important aspect that affects both local behaviors of individual members and consequently, the global response of a structure. The diaphragm action of a built structure, ...
(in Russian,diafragma,also stiffener—see [4] below). In engineering, a part of instruments, machines, mechanisms, and structures; it is usually a plate or partition (with or without an aperture). (1) A measuring diaphragm most often is a disk with an aperture. Along with the venturi an...
This relationship between the two muscle groups, with the abdominals opposing the action of the diaphragm, is known in anatomy as antagonistic. Another role of the muscle is related to its function in the abdominal cavity. As intra-thoracic pressure is reduced during diaphragmatic contraction, ...
spinal cord in the anterior roots of the third to fifth cervical segments and run downward in thephrenic nerve. According to the conventional viewpoint, the mechanical action of the diaphragm stems from a single functional entity that is attached all around the circumference of the lower thoracic...
INFLUENCE OF DIAPHRAGM ACTION UPON THE SEISMIC RESPONSE OF HIGH RISE MOMENT RESISTING BUILDING FRAMES Diaphragm or horizontal bracing system is a horizontal system transmitting lateral forces to the vertical lateral load resisting elements. Under lateral loading floor slabs in reinforced concrete building ...
This is a pure ‘piston-like’ action and has the advantage of very efficient conversion of diaphragm muscle fibre shortening into changes in lung volume. Figure 5.2, C, illustrates ‘non–piston-like’ behaviour in which the zone of apposition remains unchanged but an increase in the tension ...
In order to study how to improve the spatial action of precast monolithic composite floor slabs, and examine replacing the cast-in-place surface layer for reducing the weight of structure, we used pseudo-dynamic tests on one-quarter scale models of two-span and three-story frame structures. Th...
When the diaphragm solenoid valve is in the closed state, under the action of the spring force and the gravity of the valve core, the sealing surface of the valve core sealing block is in close contact with the annular plane of the valve seat. Since the annular plane of the valve seat ...
Diaphragm action provided by cladding panels is more and more investigated by several researchers dealing with different structural typologies. Such an as... MG De,R Landolfo,FM Mazzolani - 《Journal of Constructional Steel Research》 被引量: 5发表: 1998年 ...
The diaphragm is positioned in front of the stem. The piping, attached to the valve body, has a raised bump. When hydraulic fluid, compressed air, or manual turning action is applied, the stem presses down on the diaphragm, causing it to expand and block the piping and the fluids flowing...
