Using Sap2000 to determine dead load and live load of interior girder
Requirements:
CEIE 524 INTRODUCTION TO BRIDGE ENGINEERING Spring 2023 HOMEWORK #3 DUE DATE: 02/15/2023 1. Determine the dead load effects for interior girder (shear and moment at tenth points of different load cases). Load cases are steel self-weight, concrete deck, haunch, concrete barriers, and future wearing surface). 2. Determine the live load effects for interior girder (maximum shear and maximum moment at tenth points). Provide shear and moment values with live load distribution factors and dynamic allowance. 3. Compute factored maximum positive moment, factored maximum negative moment, factored shear of interior girder for Strength I and Service II. Project Descriptions: A two-span continous composite I-girder bridge has two equal span of 135 and a 42 deck width. The steel girders have a yield strength of Fy = 50 ksi and all concrete has a 28-day compressive strength of fc = 4.5ksi. the concrete slab is 9?? thick. A typical 2?? hauch was used in the section properties. Cocnrete barriers weighting 640 plf and an asphalt wearing surface weighing 60 psf have also been applied with a thickness of 3?. 135 108 135 108 27 27
