Among various reinforcing materials, human hair fiber (HHF) can be used as a natural fiber to enhance the shear strength and bearing capacity of a clayey soil for sustainable use of waste material and sustainable development of infrastructures in a rapid urbanization.

Many power transmission towers are situated near sloping grounds, and proper evaluation of their footing bearing capacity is essential for the safety and reliability of the critical power...

The test result reveals that the strength significantly improves with the inclusion of HHF and also prevents the sample from cracking. Moreover an environmental concern is also included by utilization of waste human hair fiber materials and they can be made useful for improving the soil characteristics and to solve the problems related to the ...

Reinforced concrete foundations, or footings, transmit loads from a structure to the supporting soil. Footings are designed based on the nature of the loading, the properties of the footing and the properties of the soil. Determine the requirements for the footing, including the loading and the nature of the supported structure.

Design the footing structure – design for the material based on applicable structural design codes which may use allowable stress design, LRFD or limit state design (concrete). Shallow Foundation Types. Considered simple and cost effective because little soil is removed or disturbed.

HHFMainly engaged in the research and development, production, sales and service of petroleum equipment and large precision forgings. It is one of the largest and most professional drilling tool stabilizer manufacturers in the country. MORE.

Footing foundations, also known as spread, combined, or mat footings, transmit design loads into the underlying soil mass through direct contact with the soil immediately beneath the footing. In contrast, pile-supported foundations transmit design loads into the adjacent soil mass through pile friction, end bearing, or both.

Footings are an important part of foundation construction. They are typically made of concrete with rebar reinforcement that has been poured into an excavated trench. The purpose of footings is to support the foundation and prevent settling.
