In this paper, the respone of H. P. —shaped cable roofs to the fluctuating wind is presented according to the random vibration theory for linear system, the assumption that the cable roofs are linear systems and the condition that the cable are preforced have been adopted. The relationships between wind speed and the displacements are shown in a series of curve lines. Various structural factors which affect the dynamic respones have been analysed and it is shown that sags of the cable roofs are the most important factor among them, therefore the cable roof structures are a kind of wind sensitive structures.

The suspended cable roof structure of the Ziho city gymnasium consists of the transversal R.C. flexural girders sealed in the upper portion of its roof and covering with the precast channel roof slabs. Its roof surface has been made of a monolithic are shape by post-tesioning method, and afterwards all joints sealed up with no.400 concrete. A series of appropriate technical measures have been duly adopted to guarantee roof-structure's safety and serviceability. Namely: increasing and strengthening of its anchorage to gurantee security of its cables against slippery and breakdown, successive tests and adjustments of cables' deflection; comparisons among hanging roof-slabs' variaties, adoption of the bentup bars in channel slabs as hooks oncables, and due considerations about concretes' contractability and thermal deformation during brestressing and sealing of its R C flexural girders etc

淄博市体育馆为悬素屋盖,上端有封闭式钢筋混凝土横向受弯大梁,屋面板采用预制槽板,施加预应力后用400号混凝土灌缝,使屋面呈弧形整体。施工中为防止挂锚时钢索拉脱及咬断钢索,增设了3道地锚并多次调整钢索垂度。挂板时经方案比较,采取槽板受力筋在端部弯起,直接挂在主索上的方法。施加预应力和封闭大梁时,考虑到混凝土的收缩及温度变形,也相应采取了技术措施。

Random vibration analysis of large span space structures or high-rise structures, which are subjected to spatially correlated filtered white noise excitations such as wind load and earthquake motion,has been a difficult problem in engineering computation. Based on the idea of discrete analysis method of random vibration, this paper attempts to solve this problem. The formulas of calculating structural mean and mean square responses are given. As an example,the wind-induced vibration of a cable roof structure is ananlysed by using these formulas.
