Building codes

Building codes are the set of norms that contain all the standards for the construction of all the building and non-building structures. It is essential to follow the guidelines given in the building codes to get the project approved by the local authorities. The engineers, architects, contractors, and all the people involved in construction activities are obligated to refer to the building codes before performing any construction activity. In the United States of America (USA), The I-Codes, which are the International Building Code (IBC) or International Residential Code (IRC), electrical codes, plumbing codes, and mechanical codes are the model codes adopted. These model codes are updated after every three years.

Please answer question 2, thanks. 1.For the loading and material information shown below, according to EC3, design and check the bending and shear capacities of steel beam which is 10 m long for carrying the listed loading. Information: Beam span length = 10 m, Bay width = 6 m, Slab depth = 20 cm, Partitions = 0.75 kN/m2 , Imposed load = 2.5 kN/m2 , Concrete density = 24 kN/m3 , Steel grade = S355 . Design the beam as a restrained beam as lateral restraint is provided by the concrete slab. Simple support condition of beam ends can be assumed. Check also the deflection of the beam and see if it can satisfy the serviceability limit states or not. 2. For the beam in Question 1, check the corresponding reduced moment capacity for high shear case assuming that VEd / Vpl, Rd = 0.7 .
Can you please solve the calculations with equations and step by step and use space Gass software for diagrams?I will be grateful to you for this help.All the best and Thank you so much in advance.
