厂房构架纵横梁因温度变化伸缩变形,从而对柱产生推力或拉力,其最不利组合对柱配筋有一定影响,不可忽视,不然将降低柱的安全度。目前国内外文献对此虽有论述,但只涉及等高构架或假定不动点位于支撑中点,而对非对称高低构架或多层的纵向构架尚未见有合理解法,本文谨就此问题,作如下探讨。代表符号: X_i——以排架左边第一柱为原点,任意i柱之水平座标: L_n——纵向排架第n层纵梁,或横向排架第n组横梁之变形不动点水平座标;
The vertical and horizontal beams of the plant structure are deformed due to temperature changes, which will generate thrust or tension on the column. The most unfavorable combination will have some influence on the column reinforcement and cannot be ignored, otherwise the safety of the column will be reduced. At present, domestic and foreign literatures have discussed this, but they only involve the contour structure or the hypothesis that the fixed point is at the midpoint of the support. However, there is no comprehension method for the asymmetrical high and low structures or the multi-layer vertical structure. This article is dedicated to this issue. Explore as follows. Symbols: X_i—The horizontal axis of the first pillar of the left shelf as the origin and the height of any i-column: L_n—The longitudinal deformation of the n-story stringers, or the horizontal deformation of the n-th crossbeam coordinate;
