ASCE 7-10 Load Combinations Spreadsheet
The sheet is designed for calculating the Unity Ratio of a member subjecting to Moment and Axial load.
This excel spreadsheet program may be used to design rectangular columns with uneven bars.
Design of columns are carried over a group of columns having a low variation of design values. In this group, design is carried for the highest values of axial force, moments about Y and Z directions, shear about Y and Z directions as well as torsion. However, it is a common practice among designers to ignore shear and torsion in columns. This practice will reduce safety factor in columns which are critical structural members responsible for the safety of the structure.
RC shear wall analysis and design excel sheet easy to use yet innovative construction spreadsheet is used to make the design of shear walls subject to wind and dead load combination. This shear wall design spreadsheet is very useful verifying constancy toward reinforced concrete structure.
It takes huge time while measuring & then remeasuring wall stiffnesses, direct and torsional rotation component of force to then estimate reinforcement and concrete stresses for a single wall successively. This shear wall design spreadsheet can significantly decrease your design time.
Presently, the sheet does not support the earlier version of excel like Excel 2003 and so on as these do not make out iferror function.
This estimating spreadsheet contains the following exclusive characteristics :

The sieve analysis, commonly known as the gradation test, is a basic essential test for all aggregate technicians. The sieve analysis determines the gradation (the distribution of aggregate particles, by size, within a given sample) in order to determine compliance with design, production control requirements, and verification specifications.
The gradation data may be used to calculate relationships between various aggregate or aggregate blends, to check compliance with such blends, and to predict trends during production by plotting gradation curves graphically, to name just a few uses. Used in conjunction with other tests, the sieve analysis is a very good quality control and quality acceptance tool.
Cantilever slabs are a typical one way slabs. They are projections from wall face of lintel beams or floor slabs. Even while designing they are considered as one-slabs with cantilever fixed or continuous at supports.
The trial depth is selected based on span/depth ratio of 7, as in IS:456. The reinforcement provided at the tension face should be checked for anchorage length near supports.
The thickness of such slabs is varied from max. at the fixed end to the min. of 100 to 150 mm at the free end. Distribution steel should be provided at the transverse direction.
Proper selection of depth and detailing of reinforcements will safeguard against excessive deflections and cracking of the cantilever slabs. Also, cantilever structural elements should be checked for safety against overturning.
