Analysis and Design for Roof of the Vertical Loads Under Sloping Roof Slabs as a Multilateral Support Plate Folded plate structure has character of “unified of borad and frame”: General intersection of each pair of ramps are for mutual support, both sides of the transition line’ plate can be counted dogleg small rotation and transmission, distribution load control which is the role of gravity the two sloping geometry load roughly symmetrical occasions, there is no corner at symmetry capital turning point, Approximate seen as the plate embedded solid take out a distance by plate of eaves, plate of inside ridge also formation to negative moment,and long roof slabs in the plate sloping beams department and neighbor plate linked together, these all can be approximated as embeddedplate edge to antisymmetric load like horizontal seismic load,the Ping roof should be treated as shear,but it is not control load usually. Plate final design moment value is the status of various unfavorable bination of linear superposition, from the crosssectional direction plate reinforced by the columns, Reference, balance the require of concrete deep beams of tectonic, upper plate for Moment of negative reinforcement should be reinforced at all or an entire crossleader, as they also serve as a deep beam distribution lumbar tendons or stirrup. plate in the bottom vertical with reinforcement eaves, Negative reinforcement in accordance with their respective calcualte requirements,and it is different after superposition stirrups requirement Both sides of stirrup in this situation cann’t linked at awnings edge follow shape “U”, can be bent to shape L follow upper and down direction,legnth of packs could equal to thickness of plate. It should enhenced at the node of ramp at the intersection appropriately. It remended that use swagger tectonic shown as in Figure 5 considing simple structure without axillary at the situation of Cloudy angle without pull. To ensure all reinforced Installing accuracy, Few of the rhombus with the supports and rebar stirrups could be added to formed positioning Skeleton at strengthening reinforced department in the figure, Let two later installed sloping steel plate tie to its lashing,designers should use a threedimensional geometric method to accurately calculate the diamond stirrups limb edge length and Forming a swagger construction plans 6. Calculating and processing of open window and hole in sloping roof Assume the plate in figure 6 has a big hole whose wideth is b ,height is h0 ,assuming that tung center along with the plane bending moment, shear, respectively are M and V through overall calculation, use vierendeel calculation method get about middle cave: 1XO MM T?? 2NR MM T?? 311 3312hVV hh? ? 0X O N RM M MV h??? Where I I2 、 I respectively represent upper and down plate limb’s Section moment of inertia and double limbs section moment of Edge Moment by hole is: 1113I M V bM? ?? 2212I M V bM ? ?? not very big by the hole, close to the neutral axis in most cases overall, under the nohole design of the reinforced the opening hole after the plane can meet the demands by calculation, under the nohole design of the reinforced the opening hole after the plane can meet the demands by calculation. General tiger window’s form prominent roof Facade which a hole had opened up and the other faces a concrete slab analysis of vertical slab roof slab surface loads ,pare with without windows and roof slabs hole window sheet increased load. profiles of window’s folded plate form make it reduce the bending stiffness pare with without hole roof board, But with the profile hole edge which parallel to the vertical plate is a partial increase in bending stiffness. In the absence of the vertical plate window subordinate legislation should have upturns beam to increase stiffness of the surrounding caves this way i can temporarily ignore the plate stiffness variation acording to the actual load, size and boundary conditions by entities plate to calculate psitive and negative moment and further processing should point out that theRoof ramp layout hole edge ideal location is near the platebending line, especially in the open side of the window because it was cut down by vertical transmission line of the moment. If the roof slab roof beams department no outward roof then the actual platebending force on the line near the roof beam reversed also true, Because of this architects should strive for when determine oosition of tiger position take appropriate pin tung far away from linebending window wall and roofing in the intersection must bear folded plate and transmission moment, but pare with plate without hole its capacity is weaken surely,and it’s node turn into weak parts. To fill thy judgment and calculation errors two panels can be double reinforcement. When the hole is less than linebending scope should increase negative reinforcement around to keep overall security plate bearing capacity. To ensure steel plate in place accuratly,also should use positioning stirrups and longitudinal reinforcement constitute skeleton similar as figure 5. Hoop end within vertical bars should be strengthen steel and end cave corner should be harvested more than one anchor length to make sure that bottom of the cave 4 tensile stress concentration. 7.
