    Lane Distribution Factor (LDF)

    For Design of pavement, for two lane one way traffic, IRC recommends that we use 0.75 x Two way traffic. ie. Lane distribution factor of 0.75 Is there any method of determining Lane Distribution Factor?

    Relay Switch to Automatically Turn on/off waterpump

    Sir, I've made a circuit using Timer IC 555 that automatically starts waterpump (1HP AC motor ) as the water level goes down & switches it off when the level rises. The circuit works fine. It has a 6VDC operated relay switch that can withstand 10Amp 250VAC. But problem is the motor, rated 1HP...

    Cut slopes & Fill slopes stability

    I'm new to this field & was wondering about the stability of cut & fill slopes. how much should be the slope to be stable? gentle is stable but steeper is economic. without any experience of similar kind, I can only rely on literature; which suggests that i should perform slope stability...

    SAP2000 RCC design yields very high reinforcement!

    I'm new to SAP2000 and this is my first attempt to design a residential building. I've done following steps: 1. Defined material 2. defined sections 3. Defined area section as Shell (thick) 3. modeled beam columns as line element & slab as area element 4. Defined load patterns>Dead, Live, Quake...

    SAP2000 Material Fe415 ,Slab is Shell or Plate?

    Hi, I wanted to define material in SAP2000. But came across some data that i hadn't used during manual design. What are these & where can i find the values for Fe 415? Minimum yield strength Minimum tensile strength Effective yield strength Effective tensile strength 2nd problem: I'm designing...

    what's chainage in road survey?!!!

    I'm confused!! Is chainage horizontal distance between IP's or the distance measured along the ground level between IP's??? If it's the horizontal distance btwn IP'S then chainage doesn't represent the actual length of the road. If it's the distance along the ground then it represents the...

    how to Create Profile & cross Section in Land development??

    Hi, I've measure Rl at regular interval of chainage. Chainage RL 0+000 Now i want to create profile of ground along CL. How can i do it? without need of creating surface. Also i have measure the vertical offsets at regular horizontal distance on both left & right side of Cl. How...

    Help!!: Raster Image to Topo Map

    Hi, I don't know if it's a stupid question. But i was longing to know, if its actually possible to convert a hardcopy of a topo. map to a digital map. I've scanned a topo map & inserted it in CAD as a Raster Image. Is it possible to draw polylines automatically along contour lines in the...

    Is it my fault in modeling? am i missing sth?

    I modeled a multistory bulding and applied various load combination to which the behaviour of structure seemed to be satisfactory. However, under the 'Envelop combination' of all combination the top floor showed some unusual behaviour (look at the attachment). I've assigned diaphragm...
