Lateral Bracing, Portals, and Sway Frames | Civil ...

07.08.2012 · The portal usually is a sway frame extending between a pair of trusses whose purpose also is to transfer the reactions from a lateral-bracing truss to the end posts of the trusses, and, thus, to the foundation. This action depends on the ability of the frame to resist transverse forces. The portal is normally a statically indeterminate frame. Because the design …

Sway and Non-sway Frames: What is the Difference Between ...

A frame is considered to be non-sway (braced) if it is sufficiently braced by lateral bracing elements like structural walls. On the other hand, frames that provide lateral resistance only through columns are considered to be sway frames (unbraced). ACI 318-19 can be used as a reference to distinguish between sway and non-sway frames.

9.6 The Slope-Deflection Method for Sway Frames | Learn ...

Consider the example sway frame shown in Figure 9.18 (this is the same sway frame that was previously shown in Figure 9.1). This frame has four total independent degrees-of-freedom: the rotations at nodes C, D and E ($\theta_C$, $\theta_D$ and $\theta_E$ as shown in the figure) plus the horizontal translation of the top beam ($\Delta_{Cx}$). The beam CDE only has one …

Portal frames - SteelConstruction.info

Portal frames are generally low-rise structures, comprising columns and horizontal or pitched rafters, connected by moment-resisting connections.Resistance to lateral and vertical actions is provided by the rigidity of the connections and the bending stiffness of the members, which is increased by a suitable haunch or deepening of the rafter sections.

36 PORTAL FRAMES - steel-insdag.org

PORTAL FRAMES Version II 36 - 1 PORTAL FRAMES 1.0 INTRODUCTION The basic structural form of portal frames was developed during the Second World War, driven by the need to achieve the low - cost building envelope. Now they are the most commonly used structural forms for single-storey industrial structures. They are constructed mainly using hot-rolled sections, …

Approximate Lateral Load Analysis by Portal Method

Portal frames, used in several Civil Engineering structures like buildings, factories, bridges have the primary purpose of transferring horizontal loads applied at their tops to their foundations. Structural requirements usually necessitate the use of statically indeterminate layout for portal frames, and approximate solutions are often used in their analyses. (i) (ii) (iii) (iv) Portal Frame ...
