In reinforced concrete structure longitudinal rebar connections are provided to ensure continuity of reinforcement. The reason that this requirement arises is the limitation in availability of a standard length of rebars. Due to transportation limits, the rebar length is normally restricted to 12 meters. In structural members, where reinforcement required length is longer than … [Read more...] about Rebar Coupler vs Lapping – Why Rebar Couplers are More Efficient and Economical?
Cracking behavior and crack patterns of ferrocement are more or less similar to reinforced concrete with some differences. Cracks, in ferrocement, at service load are very fine so that is not visible from the naked eye, and cracks in ferrocement are very small but large in numbers. Crack propagation is not sudden as it is in reinforced concrete. Progressive cracking behavior is … [Read more...] about Cracking Behavior of Ferrocement
For a building, structure design phase is the most crucial phase of a project. After the paper work completion of feasibility analysis and architectural designing, it is the responsibility of structural design engineer to bring it to reality. After receiving all the inputs from architect, geotechnical engineers and clients, a structural engineer efforts to complete the picture … [Read more...] about Structural Design Process (Steps for a Building Project)
In the field of Earthquake Engineering, many advancements are being made and engineers are investigating new techniques to minimize the risk of loss of human life and property. Various researches have been made for improving building performance under earthquake. Building codes also provides guide lines and provision based on historic records of structural behavior. While the … [Read more...] about How to Build Earthquake Resistant Buildings using Simple Techniques
Calculation of seismic loads for analysis of structure is required when earthquake resistant structure is to be designed. Structural Engineers use different design codes/guidelines for calculation of earthquake loads. Widely accepted codes for calculation of seismic loads are, Uniform Building Code 1997 (UBC-97), International building code (IBC), ASCE-7-10, Building code of … [Read more...] about Seismic Loads for Design of Structures (UBC-1997)
