2 LIMIT STATES DESIGN OF R.C. STRUCTURES INTRODUCTION • Purpose Of Structural Design: The purpose of structural design is providing a safe structure complying with the user’s requirements. The design should evolve a structural solution for safety and serviceability throughout the design life, which gives the greatest overall economy for the first cost end for maintenance costs. • Limit states: Limit states are concerned with structural safety and serviceability and cover all forms of failure. A structure could be rendered unfit for use in many ways and these factors are conveniently grouped into three major categories. – Ultimate limit states: collapse of the structure due to normal or exceptional loadings or the occurrence of exceptional events like earthquake etc. – Serviceability limit states: Deflection, cracking and vibration. – Other limit states: Fatigue, Durability, Fire resistance, Lightning etc. It is often possible that a given structure is required to satisfy...

12 Important Points for Civil Site Engineers to Remember at Site 1: In steel reinforcement works the Binding Wire required 8kg per MT , (( mt or MT ), equal to one thousand kilograms. 2: Density of Mild steel is 7850kg / m3 3: Unit weight of steel formula for 1 meter = D2 / 162 where D is Dia of steel in mm 4: Volume of One cement bag is in Cubic Meter = 0.0347 m3 which is equal to 50 kg. 5: density of Cement = 1440 kg / m3 6: Minimum thickness of slab is 125 mm. 7: Main bars in the slabs shall not be less than 8 mm. 8: Lapping length for Compression member = 50 D 9: Lapping length for Tension member = 40 D 10: Concrete fall should not more than 1.5 meter. 11: In steel reinforcement chairs minimum dia should be use 12 mm. 12: In square column we used minimum 4 Nos bar and circular column 6 Nos.
