DESIGN & ANALYSIS OF A MEDIUM-RISE BUILDING - PART 1 OF 6


EFFICIENT MODELING AND ANALYSIS

ETABS (Extended Three-Dimensional Analysis of Building Systems) is a software
that allows engineers to efficiently create structural models.

It offers various tools and functionalities that help in the quick assembly of a
building model. These include pre-defined templates, grid systems,

and a user-friendly interface that speeds up the modeling process. This
efficiency is particularly crucial in complex and high-rise building projects.


COMPREHENSIVE ANALYSIS CAPABILITIES

ETABS provides a wide range of analysis options including linear and nonlinear
static and dynamic analysis, modal analysis, seismic assessment,

and much more. This makes it a versatile tool that can handle nearly any kind of
structural engineering problem.


INTEGRATED DESIGN

One of the most significant advantages is the integrated design approach that
ETABS offers. It can automatically generate design loads and

load combinations according to various design codes, making it easier for
engineers to optimize structural elements like beams, columns, and slabs.


ACCURATE RESULTS

ETABS has been rigorously tested and validated against various benchmarks and
real-world projects. Its algorithms are designed to produce highly

accurate results, which are crucial for the safety and performance of
structures.


COST-EFFECTIVENESS

Using ETABS can lead to more optimized structural designs, which can result in
cost savings in terms of materials and labor. The software

itself may be an investment, but it often pays off by reducing project costs.


INTEROPERABILITY

ETABS can interface with other software, making it easier to integrate it into a
multi-tool workflow. This is particularly useful in projects

that require collaboration between professionals from different disciplines.


CONTINUOUS UPDATES AND SUPPORT

The software is regularly updated to include new features and to be compliant
with the latest design codes. Technical support is also readily

available, making it easier for engineers to resolve any issues they encounter.

PRECAST LIFTING CALCULATION

Lifting Calcution is very important to secure the safety during the lifting of
the elements.

Certainly! As a Structural Engineer and software developer, you can appreciate
the importance of precise calculations,

especially when it comes to lifting precast concrete elements. Here's an
explanation of the importance of precast lifting

calculations.

Importance of Precast Lifting Calculation:

1. Safety: The foremost reason is safety. Incorrect lifting calculations can
lead to accidents,

jeopardizing the safety of workers and damaging property.

2. Financial Considerations: Any mistake during lifting can lead to damage to
the precast element.

Given the cost associated with precasting, damages can be financially
significant.

3. Project Schedule: A lifting failure can set a project back significantly in
terms of time,

especially if a replacement for the damaged unit needs to be manufactured.

4. Reputation: Mistakes in lifting can damage the reputation of the company or
contractor,

affecting future business opportunities.

5. Efficiency: Proper lifting calculations allow for smooth and efficient
operations on-site,

minimizing delays and maximizing productivity.

Footing Calculator




INPUT DATA:

Length (m):
Width (m):
Depth (m):
Concrete Mix Class: Class AA (1:1.5:3) Class A (1:2:4) Class B (1:2.5:5) Class C
(1:3:6)


RESULTS:

Volume of Footing: 0 m³

Quantity of Cement: 10.91 bags

Quantity of Sand: 0.57 m³

Quantity of Gravel: 1.15 m³


MANUAL SOLUTION:

Given:
Length = 3.5m
Width = 2m
Depth = 0.3m
Mix Ratio = 1:1.5:3

1. Calculate the volume of the footing:
Volume = Length x Width x Depth
Volume = 3.5 x 2 x 0.3 = 2.10m³

2. Based on the selected mix ratio:
Total Mix Volume = 5.5

Cement Volume = Total Volume x (Cement Ratio / Total Mix Volume)
Cement Volume = 2.10 x (1/5.5) = 0.38m³

Sand Volume = 2.10 x (1.5/5.5) = 0.57m³

Gravel Volume = 2.10 x (3/5.5) = 1.15m³

3. Convert cement volume to bags:
No. of Cement Bags = Cement Volume / Volume per Bag (0.035m³)
No. of Cement Bags = 0.38/0.035 = 10.91 bags

DEFLECTION CALCULATOR (ACI 318-19)

© RHC ENGINEERING, 2023. ALL RIGHTS RESERVED.

This is a Beam Deflection Calculator based on ACI 318-19 standards. It
calculates the deflection

of a beam under uniformly distributed loads and also shows whether the
calculated deflection is safe based on allowable deflections.


q = kN/m

L = m

f'c = MPa

b = m

h = m



where:

q is the uniformly distributed load in kN/m

L is the length of the beam in m

f'c is the concrete compressive strength in MPa

b is the width of the rectangle concrete beam in m

h is the height/depth of the rectangle concrete beam in m

Calculated Deflection: - mm

Allowable Deflection L/360: - mm

Allowable Deflection L/240: - mm
