STEEL STRUCTURES

A 20ft long simply supported beam is made of W21X55 with fy=50ksi. The service distributed loads on the beam are DL=2k/ft (including self weight), LL=4 k/ft. Show if the beam is adequate for shear.

I need information regarding fatigue cracking and block cracking in flexible pavements, information should include but not limited to ; causes, severity levels,measurement methods, maintenance procedures and preventive measures.

please write 3 or more references.

Thank you!

1. A new entrance road to the pump station will be constructed using crushed stone. The road is 675’ long, 27’ wide, and 18” thick. The road will be constructed using a dozer and self-propelled tamping foot roller. The dozer has a power-shit transmission and a rated blade capacity of 6 LCY and pushing a distance of 100 feet per cycle. Maximum reverse speed is 4 MPH. It will spread the rock in 6” lifts. The compactor will follow each spreading lift with 3 passes. The compactor width is 6 feet and speed per pass is 1.5 MPH. Job efficiency is assumed to be 50 minutes per hour for both operations.  How much crushed stone (rock) is required? (LCY)  How long will it take to spread the rock? (Hours)  How long should it take to compact the rock?(Hours)

idk we werent given that info

what is cradle to grave, grave to the gate boundary and define each steps with an example

Maximum instantaneous discharges of a river from 1926 to 1951 are given in Table. First, determine average, variance, skewness, PDF and CDF of this time-series. Secondly, fit probability distributions of exponential, normal and Pearson and find out which one is the better. Calculate the flood discharges during the next 5, 10 and 50 years.

A sag vertical curve (equal tangent) has PVI at station 212+00 and elevation 540.75 ft. The initial grade is -2.5% and the final grade is +4.5%. The length of the curve is 900 ft. Determine the following,

1. Stationing of the low point, PVC, and PVT.

2. Elevation at station 213+00, PVC, low point, and PVT.

You are a contractor on a $45 million project in down town Los Angeles. The project is scheduled to be completed in 2 years. You are 6 months into the project so far and project performance reports indicate that the budget has been exceeded by 10% thus far. Your schedule has also been delayed by more than a month due to subcontractor issues and labor disagreements. As a result, the quality of the job is suffering. It is your job as the Project Manager to get the project back on budget and schedule and address any quality issues. What steps will you take in order to get the job back on track? Identify actions that you could take and analyze which ones might work best.

1.There are just too many vehicles in Malaysian cities. Are cities being designed to accommodate vehicles and not people?

based on engineer and society subject,pls try to elaborate the topic not more than 5 pages and pls include the reference also

research a topic related to Islamic Architecture such as:

Period, Building or Element,

The project focuses on the following:

• Short history of an era and region

• Cultural, philosophical, contextual, etc. approach to the design

• Brief description and explanation (bullet points)

• Most important characteristics & features

• Comparison (similarities and differences) between styles, buildings, construction methods, materials, decoration, theoretical backgrounds, etc.

• Findings and final observations of the research

The bellow listed titles are just your guidelines. You can either select from the listed topics or suggest another one that is following the same idea of the comparative analysis:

1. Traditional Islamic Architecture versus Modern Islamic Architecture

2. Islamic Architecture in Iran versus Islamic Architecture in India

3. Great Mosque of Damascus versus Great Mosque of Cordoba

4. Hammam in Morocco versus Hammam in Turkey

5. Traditional Hammam Design versus Modern Hammam Design

6. Hypostyle Hall versus Central Dome Concept

7. Mosques of 17th Century: Jama Masjid-Delhi versus Sultan Ahmed Mosque-Istanbul

8. Contemporary Mosque in Turkey versus Ottoman Mosque in Turkey

9. Grand Mosque of Bursa versus Seljuk Architecture

10. Traditional Decoration and Ornamentation versus Contemporary Decorative Style

11. State Mosque: Gazi-Husrev Bay Mosque-Sarajevo versus Suleymaniye MosqueIstanbul
