1) a) As i understand this is a concrete beam crack which occurs due to corossion or insufficient concrete cover. As the lower section of the beam is exposed to the environment so the lower or the side face of the beam faces these cracks and it can be said as bottom reinforcement crack along the length. If we talk about…

I have attached my answers in the attachment 

1) Firstly the plan is not symmetric as structure simplicity and symmetry plays a very vital role in safety of the building so symmetry and regularity in the elevation is also must this has a symmetry structure above leaving the lowest part more narrow which disobey the fact of symmetry some where and also regularity of…

The answers are attached with pictures.

1)    Shear walls in the plan should be symmetrically located to reduce the twist or collapse effect. As it experiences the maximum effect of lateral forces it also reduces the lateral displacement under the effects comming upon. Its main function is to provide the lateral strength to the building to resist the…

PROCEDURE TO BE FOLLOWED: Open the ETABS software  click the file menu and choose to create a new modal option after choosing a new model a dialogue box will appear  choose the built in setting option and select the display unit after the modal is intialized select the grid and storey inputs from the new modal…

Step-01 After Downloading the challenge open it in Etabs we have run the analysis very first Step-02 From the display option , select show tables  After selecting show tables, go to analysis output then select modal participating mass ratios and click on the ok button This table of modal mass ratio will be visible…

Step-01 After downloading the challenge open it in Etabs 18 first  Step-02 Now we will check the design preferences Step-03  Now we will go for design check for all member We can the details by moving the curser to the beam  Step-03 We need to draw the reinforcement diagram of span3 continuous beam and also…

Providing isolated footing  Square footing  column size=400x400 Axial load=2000kN Soil Bearing capacity= 150KN/m2 Grade of concrete(fck)=M25   Size of footing: Assuming self weight of footing equals to 10% of superimposed load =10% x 2000 =.1x2000 =200KN Total load=200+2000          …

Introduction: Column is a Structural vertical member which basically carries compressive loads  Columns are primarily intended to resist the longitudinal compressive forces Columns are classified as short, intermediate or long depending on their lengths, their material or there type Process to be followed: Step-01…

AIM:- To compare Fundamental natural periods of building E & F as well as G & H and the significance difference. Fundamental natural periods of building H,J and K also as have the building have become flexible or stiff due to change in mass Fundamental natural period of building A, B, F and H with change in…

Aim: To create a modal of G+7 building given in the architectural drawings as per the provisions of IS 1893 and IS 13920 followed by response spectrum analysis. PROCEDURE/ STEPS TO BE FOLLOWED: Plan is plotted according to the dimensions given in the architectural plan. Next we will add material properties as grade of…

AIM: 01 Model the isolated footing provided in week 11 on SAFE, analyse and design it to verify the size, depth and steel provided as per calculations. PROCESS/ STEPS TO BE FOLLED: Open the safe software  change the IS code and unit system   Select single footing  A tabular box will occur  Change the…

AIM: To design and analyse G+3 hostel building in Etabs and foundation in CSI SAFE. INTRODUCTION:  The procedure for the analysis and design of a given building will depend on the type of building, no. of storeys, building's complexity and many more. The procedure for structural design will involve many steps…
