Hi! I'm designing a bridge bent with two piers having unbraced heights 15.2m and 8.2m. Originally, the bridge was planned with both piers having equal heights of 15.2m but that is not a feasible option because of too much cut (the terrain is mountainous with closely spaced contours) so I have to...
Hi! We are designing a single span bridge comprising spill-through abutments at the ends instead of retaining wall abutments. The abutments are initially planned as pile bent piers with height (till depth of fixity from NGL) approximately 15m. The piers will protrude from the fill for 3m till...
Hi! I'm modeling a building (Flat plate system) on a non-linear analysis program. The program doesn't support loading on slab elements or any other area elements for that matter, it only has the option to load line elements and nodes. So, I'm trying to convert the slab loads into nodal loads and...
I am doing a case study on a two-span bridge for help in designing a similar one but in an area of high seismic activity. The case-study bridge is constructed on a controlled channel, lined with concrete, and with 10ft depth and 10ft/s stream velocity. The designer has provided a hefty skew of...
Hi! A complete novice here. I'm designing a bridge pier (L=26m, D=1.8m, laterally braced at mid-height. Using CSI Bridge). I was analyzing the design data when I saw that the value of Delta_b (Moment magnification factor for non-sway moments) was 2.093. I know that the ACI 318 limits the...
Hello guys! I have just started learning the API functionality of CSI SAP2000 and need help regarding the section designer. I've defined the column sections using the "SetSDSection" function. The function just defines a new section and sets the concrete strength and design preferences e.g...
