工业和民用建筑中,钢结构框架常成为多(高)层结构的一种形式,但框架横梁中的正弯矩值,在一定的荷载条件作用下,是随框架跨度增大而增大,导致横梁截面增大,用材增加。如能在设计中设法调整梁中与梁端弯矩值,并使二者绝对值尽量接近,利用和充分发挥钢材各向同性特点,就将有可能达到经济用材的目的。办法之一,可以考虑将框架横梁两端向柱外延伸构成悬臂梁,并借助一般建筑围护外墙的重量,将外墙直接悬挂或支承在悬
In industrial and civil buildings, the steel frame often becomes a form of a multi-layer (high) layer structure, but the positive moment moment in the frame beam increases with the increase of the frame span under certain load conditions. As a result, the cross-section of the beam is increased and the material is increased. If we can manage to adjust the bending moment of beam and beam ends in the design, and make the absolute value of the two as close as possible, and make full use of the isotropic characteristics of steel, it will be possible to achieve the purpose of economic timber. One of the measures can be considered to extend the two ends of the frame beam to the outside of the column to form a cantilever beam, and use the weight of the general building to enclose the external wall to directly hang or support the external wall on the suspension.
