anyone have experience with setting slopes for outdoor, asphalt paved playing surfaces? arch. graph standards recommends slope range of .83% - 1% for tennis courts, but typically parking lots have min. of 2% to prevent bird baths. is 2% too steep to play basketball? the court will slope...
I am reviewing the structural design of precast box culvert manufacturer and need some clarification. The culvert will be produced as "clam shell" sections (upper and lower halves) with shear key to prevent lateral movement. When analyzing as a frame using moment distribution, I am unsure...
In designing a sanitary sewer for an existing neighborhood, I wanted to know the standard way to determine stationing. For example, using the roadway centerline is difficult since the streets are very narrow (15'), lack curbing, and constantly change direction. Also, the property lines (some...
I'm currently working on a design for a sanitary sewer. The neighborhood currently utilizes septic tanks, drainage fields. I'm concerned with the lack of flow in the sewers since very few homes will be connected. I realize I need to increase slope but then my manholes/pipe will become...
I have a building that has an existing built-in gutter which is "hung" on the wall. We want to remove the gutter, install a new frame (looks like this < ) with the 2 members attached to boards along the wall. My question is: how should I connect member to member (bolted next to each...
In designing an infiltration basin (40% voids, assume size is 20'L x 6'w x 3'd), how should I determine the hydraulic gradient? If i = h/L, is h the depth of water in the basin (3'). Is L also the depth of the basin (3'), thus i = 3/3 = 1. Unless stormwater is ponding above the basin, is there...
