Design a rectangular pre-stressed beam section (on allowable stress basis) that supports a live load of 2.5 k/ft on a span of 30 ft. Pre-stress losses = 22%. fc 6000 psi, ftt = -208 psi, fct = 2880 psi, fcs = 3600 psi, fts = -465 psi.

1.A rectangular beam of 12 in. width and 18 in. depth is pre-stressed by a force of 20 kip applied through a tendon of wires of 2 in. diameter located 3 in. from the bottom. The beam carries a load of 2 k/ft over a span of 20 ft. The pre-stress losses are 25%. Compute […]

Design a beam of A992 steel for the loading shown in Figure P11.2.

1.Design a beam of A992 steel for the loading shown in Figure P11.2. The compression flange bracing is provided at each concentrated load. The selected section should be such that the full lateral support condition is satisfied. Determine the maximum unbraced length of beam to satisfy the requirement of adequate lateral support. 2. Design a […]

How much fees could HFRI replication charge before falling below S&P Sharpe ratio?

1. How has DELTA done vs. HFRI_FW and S&P index? Compute the mean return, volatility, Sharpe ratio, and correlations of DELTA with the indices, for the whole period as well as two subperiods (2008-2009 and 2010-2011). What is the simple cumulative return for DELTA and HFRI_FW and S&P index in the whole period from 2008 […]
