    Slab to wall connection - couplers

    I have a tower project where walls are build ahead of the slabs with self climbing formwork. Connection of slabs to walls is achieved with couplers. In some cases we use starter boxes but can't use them everywhere and couplers are required. Now, the Contractor failed miserably to install...

    Coupling beams - diagonal reinforcement

    I have a RC building with with short coupling beams in coupled wall system. The short coupling beams designed with diagonal reinforcement as seen on the image on the left. Due to a number of site reasons in many cases they end up on site more like the right image below. They are slightly...

    Shear reinforcement - Foundation slab

    Can I have an opinion on whether these are contributing at all in shear resistance of a (piled) foundation slab? On my construction site the designer said yes but I have doubts. In my designs I never considered them, nor I have seen a code reference (in any code) that says you can consider...

    Reinforcement Laps - RC section resistance

    I've seen a few different opinions on the matter, so would like to ask the community as well. In a RC moment joint, (say culvert wall base) what is the reinforcement for Section Resistance (bending)? Can we add the starter bars to the main wall bars (lapped) to determine the resistance? If so...

    Wave actions - dynamic analysis

    Hi everyone, I design a 2-storey steel building on a jetty head which is 100m into the sea. The water depth to seabed is shallow and waves are small (Mean SWL 4m+3m storm surge, Significant wave 2.5m). The jetty is a set of unbraced steel hollow sections (Diameter 457x16) @5m centres. I want...

    Bridge Engineering Literature

    Hello everyone, I am a young civil engineer and I am having an interview soon for a bridge engineering role (highways). I have a pretty good background in all the aspects of structural engineering (Structural mechanics, Concrete, Steel, Composites, Dynamics) but nothing specific in bridge...
