In this Article Learn : Various methods used for the design of R.C.C. structures,Working stress method,Load factor or ultimate load method,Limit state method, The main drawbacks of the working stress method of design,the advantages of Ultimate load method,The main limitations of the ultimate load method,The two important limit states to be considered in design:Limit State of Collapse,Limit State of Serviceability. DESIGN PHILOSOPHIES Design of any R.C.C. member comprises of the following : (i)        To decide the size (dimensions) of the member and the amount of reinforcement required. (ii)       To check whether the adopted section will perform safely and satisfactory during the life time of the structure.             Various methods used for the design of R.C.C. structures are as follows : (i)        Working stress method. (ii)       Load factor or ultimate load method. (iii)     Limit state method.  Working Stress method This method of design was the oldest one. It is based on the…

Dead loads, Live load or imposed load, Wind load, Snow Load,Earthquake loads.

In this Article: Learn Types of loads on R.C.C. Structures, Dead loads, Live loads or imposed loads, Wind loads, Snow Loads,Earthquake loads. See also The loads coming on the foundations TYPES OF LOADS ON R.C.C. STRUCTURES Structures are designed to withstand various types of loads. The various types of loads expected on a structure are as follows : (i)        Dead loads (ii)       Live loads or imposed loads (iii)     Wind loads (iv)      Snow loads (v)       Earthquake loads   Dead Loads Dead loads are due to self weight of the structure. Dead loads are the permanent loads which are always present. Dead loads depends upon the unit weight of the material. Dead loads includes, the self weight of walls, floors beams, columns etc. and also the permanent fixtures present in the structure. The unit weight of commonly used building materials are given in the code IS 875 (part-I)-1987. The unit weights of…
