Embodiment Construction

[0013] Embodiments of the present invention will be shown in detail below in conjunction with the accompanying drawings.

[0014] Depend on Figure 1 to Figure 3 As shown, a wind-resistant wall with a portal frame with special-shaped columns, the basic composition of the wind-resistant wall with a portal frame with special-shaped columns includes: rigid frame columns 1, oblique beams 2, wall purlins 3, corner braces 4. Tie rod 5; the rigid frame column 1 is connected to the inclined beam 2, the inclined beam 2 is connected to the inclined beam 2, the wall purlin 3 is connected to the rigid frame column 1 in the horizontal direction, and the corner brace 4 is connected to the wall purlin 3 and the rigid frame The column 1 is connected, and the tie rod 5 is connected with the wall purlin 3 and the rigid frame column (1).

[0015] The rigid frame column 1 is composed of a T-shaped column and an H-shaped column, specifically, a T-shaped section column is welded in the normal dire...

Abstract

The invention relates to application of special-shaped steel columns in portal rigid frames, particularly relates to portal rigid frames with spans not longer than 20m, and discloses a wind-resistant wall with a portal rigid frame comprising special-shaped columns. The characteristic of high bidirectional rigidity of each special-shaped column is sufficiently utilized, so that wind-resistant columns can be omitted or only a few wind-resistant columns are required when the portal rigid frame is designed. Besides, as the span of wall-surface purline is increased, the wind-resistant wall is provided with diagonal members for pulling the wall-surface purline, and the self-weight mid-span deflection cannot be not excessively high. In addition, the wind-resistant wall is provided with angle braces, so that the wall-surface purline is guaranteed against deforming excessively under the action of a wind load. The wind-resistant wall has the advantages that consumption of steel materials can be effectively reduced, the quantity of foundations can be reduced owing to the fact that the wind-resistant columns are omitted or the quantity of the wind-resistant columns is reduced, and engineering construction is facilitated.

Description

technical field [0001] The invention relates to an improved application of a wind-resistant wall in a portal-type rigid frame, and is suitable for a gable-shaped portal-type rigid frame with a span not exceeding 20m. Background technique [0002] Portal frame is a kind of steel structure widely used in our country. However, the portal frame is an in-plane structural system, and its longitudinal wind load and other longitudinal external loads are borne by the two frames with wind-resistant columns at both ends. These two frames are called doors. Wind-resistant wall with rigid frame. The other rigid frames are connected longitudinally by tie rods to transmit the longitudinal force to the inter-column support and the wind-resistant wall. However, the setting of the wind-resistant columns will increase the amount of steel used, and at the same time, an independent foundation must be poured at the lower end of the wind-resistant columns, which will increase the amount of work. ...
